How a Laboratory Course Can Help Your Career

How a Laboratory Course Can Help Your CareerIf you are looking for a learning experience that will help you understand what is involved in the formulas used in Formula Mass Definition Chemistry, you are not alone. Many students, even in this economy, do not have the time or the money to pursue a Bachelor's degree.For many students who have just finished their undergraduate degree, an instructor-prepared lab course seems like a step backwards. This is especially true when compared to the high level of instruction that a professional teacher provides in a laboratory setting. It is the most cost effective way to get the skills and knowledge necessary to get a career in science.The goal of Formula Mass Definition Chemistry is to give students the skills and knowledge to explore a variety of situations involving their profession. A lesson plan that includes all of the required reading and lecture material can take many months to complete. A comprehensive lab will allow students to perform multiple experiments at the same time, so that they can test each solution to see which works best in a variety of different settings.The emphasis on repeatability for these laboratory projects helps students learn to identify common mistakes that occur during the course of a given experiment. This can help to ensure that students are not repeating those mistakes in other areas of their career, such as finance.A laboratory course can provide a variety of projects that focus on different aspects of Formula Mass Definition Chemistry. Students can work with light, chemical compounds, light, gas, radiation, and mass spectrometry. The student will be able to choose a project based on his or her interests, then the instructor or the advisor will guide the student through the process of choosing a project.Since students have options for the coursework they choose, they can select courses that are less demanding than other grades. A grade that emphasizes learning in the lab can help studen ts complete their bachelor's degree in three years. More importantly, it can give them a foundation for careers in business, law, medicine, or academia.Regardless of whether students opt for a traditional classroom learning environment or online lessons, there is a program out there that meets the needs of students who want to take up Chemical Sciences in their own homes. Learning in the lab can help students understand the basics of chemistry better, which can help them to feel more confident about applying this knowledge in their professional careers. Whether you plan to pursue a professional career in the area of the sciences, or simply want to gain insight into the entire subject, there is no substitute for a professional lab instructor.

How to Improve Your Mental Maths Calculation Speed

How to Improve Your Mental Maths Calculation Speed For a lucky few, maths and numbers come easily. However, most of us have to work to be good at maths. Though we all carry phones in our pockets equipped with basic calculators, it comes in handy to be able to complete simple maths problems off the cuff. Understanding percentages so you can quickly leave a tip at a restaurant is both convenient and easy. Keeping track of your finances is a necessity. If you let it, maths can help you get through your day. So brush up on those maths skills! Here are some easy ways to do it: Go digital Though parents may want to deny it, playing video games can improve your mental recall and maths skills. Apps are cheap and easy to use, no matter where you are, and there are several out there specifically designed to sharpen users' maths skills. Lumosity Brain Trainer is free and uses simple visual math puzzles to educate. Mencal is more like a quiz in that the app provides you with lessons before testing you on your number skills. If you have a phone or a computer nearby, practicing your maths know-how this way is both convenient and fun. Test yourself throughout your day Do simple maths in your head as you go about everyday activities. Try calculating how much money you'll spend on fuel, taking into account how big your petrol tank is and the price per gallon at the pump. If you enjoy baking, work on your fractions by doubling your batch of banana bread ingredients - whether or not you actually make twice the amount is up to you. (Though who wouldn't want twice the banana bread, right?) Try to challenge yourself to get better at maths while doing everyday activities. Eat your breakfast Countless studies prove eating breakfast, especially one containing a decent amount of protein, improves cognitive function. Starting off with a healthy morning meal gets your brain going and helps it perform throughout the day. Some quick and tasty morning meal ideas include yogurt and granola or peanut butter with banana on a slice of multigrain toast. Stock your fridge with healthy foods you enjoy, and you're way more likely to reach for them in the wee morning hours. Turn up the tunes Listening to music stimulates brain activity, and studies show that it can also aid your reasoning skills. Reasoning and problem solving go hand in hand, so it only makes sense that listening to music can also improve your math. Classical music is most often highlighted for its positive effects on the brain, so try blasting some Mozart next time you attempt long division. Sharp maths skills can help you file your taxes, calculate a tip, keep score at darts, and calculate your data usage for a mobile phone plan. These are just a few situations where maths comes in handy. You may find as you move through higher education and into the workplace that being able to do basic maths quickly is super useful and maybe even surprisingly easy.

Irvine ACT Tutor Tips New PreACT Test Announced

Irvine ACT Tutor Tips New PreACT Test Announced Tips from a Private Irvine ACT Tutor: New PreACT Test Announced Tips from a Private Irvine ACT Tutor: New PreACT Test Announced The makers of the ACT have announced that there will now be a pre-testing system available to 10th graders. Many students take the ACT in the 11th grade only to find that they werent prepared and have not achieved the score they need to apply to their dream school its never too early to book your private Irvine ACT tutor from TutorNerds. There is now a PreACT that is administered a year earlier, allowing students to change their study habits and focus with enough time to meet their collegiate goals. Additionally, Educators have been told that the PreACT is shorter than the ACT, so students dont have to spend an entire day in the testing room. So what does this mean for current high school students and their parents? 1. Planning ahead Although many students and parents feel there are already enough standardized exams, taking a shortened version of the ACT designed for a 10th grader can help families plan ahead. 10th grade is a transitional year where students will have to begin to pick an academic path even though they are still an underclassman. If a student does well on the exam, its a nice breather for them. Additionally, their parents should know that things are going well, and the student is reaching their target. On the other hand, a student who performs poorly on the test, either due to lack of knowledge or lack of study habits, will have plenty of time to make some changes before college applications (READ: 5 things to do over spring break with no hassle). 2. Picking the right exam Students have the option to choose between the ACT, SAT, or both. Although a few universities do have a preference, at this point its mostly up to the student. Now that the PreACT is available, students will be able to make their choice earlier and get an idea about which test best aligns with their skill set. More test prep options equate to more flexibility when applying to college and allows students to fit the test to their talents and experience. 3. Focusing on improvement The 10th grade is a transitional time where many students are dealing with growing up, meeting academic benchmarks, and socialization. The first two years of high school are pretty overwhelming, and many students start to get really it together academically when they are already well into their college prep years. If students know that, for example, they are on target with math but need a lot of help with their reading comprehension skills, they have plenty of time to focus on those elements before sending out college applications (READ: ACT Tips From a Private Irvine Tutor). 4. Identifying a natural skill set Most students have a talent in either math or English.   A few are talented in both. Its a good idea to identify where a students natural skills are because they may have changed since elementary and middle school. Some kids who loved to read when they were eight will struggle with it when they start reading complex novels and texts. Others may have superior math skills up to a point and then need a little bit of extra help. Pre-tests can help students identify and work on these issues. 5. College prep and applications The 11th and 12th grades now essentially serve as the college prep years. Students decide before they enter the 11th grade if they will be taking AP courses, and start thinking about what universities they are interested in. One of the elements of college prep, in general, is to learn how to take standardized exams successfully. This means learning test prep in addition to understanding the actual material. Pre-testing allows students to have this information a year earlier. Score high on the ACT with the help of an Irvine private ACT tutor! Call us today for more information.

Discount Tutor Shack Promotions

Discount Tutor Shack PromotionsTutor Shack and other unique toy shops have been around for decades in the USA. The business started off selling blank coloring pages as a means of teaching children how to color. Some would use the pages to learn different colors that they might not have seen before.These small stores were often around early on in the color wars between the popular kids colors red and blue. Some used this as a way to give kids the perfect incentive to try to sell their color. It was something they could do to earn a little extra money, even though they had nothing to color!More recently, the business has become a place for the trusted color names to do some marketing. These toy stores are known to sponsor a particular type of sports event or special event. They will offer special toys for the sports fan. Some of these come with a player named after the store.For example, if you were buying some specially made teddy bears for your child for Christmas, a small part of th e sale would be getting the same toy from this particular store. Other promotions are toys of good luck, prizes or even their signature gumball machines. These are events that are quite rare but could happen if they feel they can give you an advantage.If you're thinking about trying to get your business at Tutor Shack, be sure to find out whether there are any special events they will be sponsoring. Then just ask if you can use their space for your business promotion.Although you'll probably have to pay for this as this is considered as a special event, you'll be able to advertise your business more effectively than you could on your own. Just make sure you've got a good eye for what kind of events will work best for your business and make sure they will be invited to the events that Tutor Shack has gone on. Even if you have your own business, you can still find great deals for Tutor Shack when you shop there. Look online to see if they have any special sales events.

Not sure what type of paint you should be using or which techniques you should be learning?Painting tutorials can cover plenty of different techniques and mediums (graphite pencils, Indian ink, pastels, poster paints, watercolours, sanguine drawing, charcoal, oil paints, etc.).But what about acrylics? Where do they come from?Acrylic paints are a recent invention. (Source: HoliHo)According to Wikipedia, “Acrylic pai nt is a fast-drying paint made of pigment suspended in acrylic polymer emulsion.”This type of paint is relatively new in comparison to older types of paint like watercolours. Oil paints have also been around for about 500 years. The story of acrylic paint starts more recently.Synthetic paints first appeared in the 1930s in the United States of America. The paint was initially used to paint cars and buildings. However, some artists started using this paint for their works.Artists like Barnett Newman and Marris Louis used their paint mixed with turpentine to paint their works.The paint as we know it today was really invented in 1963. The chemist Henry Levinson invented this paint which could be diluted in water to make it more useful for art.The first brand of this type of acrylic paint was called Liquitex. It was made famous by Andy Warhol who regularly used it in his work.Acrylics started becoming popular in Europe in the 1960s after Pierre Alechinsky discovered them while in the United States.The paint today is made from ground synthetic or natural pigments.  It is then mixed with water and acrylic resin in order to give it its final texture.Learn more about the differences between acrylics, oils and pastels!Why Use Acrylic Paints?What is so special about acrylic paint and what are the advantages of using it?Acrylic paints can be really easy to use. Once they're mixed with a bit of water, they're very easy to paint with.It can be used on a wide range of supports and surfaces making it many artists’ favourite type of paint.However, acrylic paint, unlike oil paint, dries very quickly. It’s therefore very difficult to go back to your work in order to change the colours.Acrylics can be a great way to express your creativity. (Source: bilgecangurer)This can also be its biggest strength. You don’t have to wait weeks for the layers to dry like you have to with oil painting.  That said, some painters do leave their acrylics to dry for a bit longer.Acrylic pai nt can also be used to base your work before painting on a stretched canvas with oils. It doesn’t quite work the other way round, though.You can use acrylics for a variety of different pieces. It’s one of the most common types of paint used in art classes, painting tutorials, and online art classes.  I’ve always loved painting with acrylics.It’s also very easy to quickly copy the greats like Monet, Courbet, Delacroix, Dali, Da Vinci, Picasso, Cézanne, Degas, Rubens, Botticelli, Renoir, Rembrandt, Van Gogh, or Manet.Check here for the best painting courses here.

This paint will also act as the background to your work. If your composition is light, avoid using a dark colour for the base.Make sure that the paint is slightly diluted. Choose a colour close to the main colour of your piece.  Some artists paint shapes directly onto the canvas with a brush. If you’re not sure of yourself, you can sketch with charcoal, chalk, graphite pencils , etc.These are painting classes near me you can take.Unlike watercolours, acrylics won't wash if you add water once it's dried. (Source: Pexels)You’ll need to add colour to your work, too. Start with the background objects first. Even if you make a mistake, you can always go back over it later with the elements in the foreground.Go from the lightest to the darkest colours.  You’ll finish by adding the dark shadows to your piece in order to give it depth.

Statistics Practice Problems

Statistics Practice Problems How to Pass your Statistics Exam ChaptersBasic Statistics ComputationsQuestion 1: Build a Box Plot Based off of the Following Stem and Leaf PlotQuestion 2: How to Calculate and Interpret the Correlation CoefficientQuestion 3: How to Interpret Statistical TestsGet Extra Statistics HelpWhether you’re studying for AP Statistics, A-level exams, or just need some extra help with your coursework, these practice problems will give you the extra help you need. While statistical methods of analysis and statistical modeling are often linked directly with data analysis, it is important to understand the arithmetic at the root of these analytic methods.While most software packages, like SPSS and Stata require little to no computation on behalf of the statistician, it is important to know how these software work. At the root of most of your statistical analysis is a branch of mathematics called Bayesian statistics. It is not likely that you will have to deal with Baye’s theorem after your first introductory statistics course , but it is important to always remember the implications of it on what’s known as Bayesian inference.In statistics, you use inference to be able to predict the likelihood of specific events based on previous, observational data.Baye’s theorem uses probability to describe the likelihood of an event happening given previous information of that same event occurring, also called a prior. For example, if you would like to calculate the probability that the ice cream truck in your neighborhood will come to day, given that it is a sunny day, you can use previous, empirical data to estimate how likely it is that you will get your cone today.The definition of Bayesian inference, then, is deducing the likelihood of an event from a population distribution using Baye’s theorem. This is the basis of many statistics problems and tests you will encounter, and it is important to remember because many times you will not see it explicitly. This guide will offer three sections of examples that jump off from this theory, each section building on this theory.

Most likely, you have taken an introduction to probability and understand the importance of conditional probability in building even the most simple exploratory data analysis. Statistics and probability go hand and hand, which is why it’s important to understand before practicing these problems.The definitions and skills you need to understand to work out the problems in this section include:Central Limit TheoryCentral TendencyStandard Normal DistributionSample Mean, Median and ModeQuestion 1: Build a Box Plot Based off of the Following Stem and Leaf PlotBoth the box plot and the stem and leaf diagrams are different ways of displaying the distribution of a particular variable in your data. The difference is that a box plot displays how your data is distributed based on a normal distribution. In order to be able to build the box plot, is important to understand what each point on the plot represents.The median is middle, where 1, 2, 3, and 4 represent the four different quartiles of your data. Meaning, if we take the first quartile, this means that 25% of your data lie in this region. At quartil e 3, this means that 75% of your data lie at that point and below. Quartile 0 represents the minimum and quartile 4 represents the maximum. This is then compared to a normal distribution:A recurring feature in statistics, understanding a normal distribution is keyLooking at the picture above, we can see that about 50% of our data will fall between Q1 and Q3. Below Q1 or above Q3, only about 25% of our data lies. Beyond the minimum and maximum, these data points are considered outliers. An outlier is a data point that is not normal in relation to the sample population. Understanding this information, we can calculate that given this stem and leaf plot:Stem-and-leaf plots can often be a great way to understand dataOur box-plot that looks like:Master your box-plot interpretation skills AisvaryaData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors AdeyemiData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors AdenikeData Analysis Teacher 5. 00 (4) £25/h1st lesson free!Discover all our tutors GokhanData Analysis Teacher 5.00 (4) £30/h1st lesson free!Discover all our tutors OlawaleData Analysis Teacher £12/h1st lesson free!Discover all our tutors ThanushanData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors AisvaranData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors Muhammad umairData Analysis Teacher 5.00 (2) £100/h1st lesson free!Discover all our tutorsQuestion 2: How to Calculate and Interpret the Correlation CoefficientBuilding on the last section, it is important to understand how particular variables within your data set relate to one another. This is especially useful because regardless of the types of data you will come across, you will be able to apply these tools regardless of what kinds of statistical concepts you are using. One important table that you will encounter is a correlation and covariance table between the variables in your dataset.Whereas the definition of correlation is the strength of the relationship between two variables, the covariance refers to how these two variables vary together. The objective of these numbers is to be able to measure how closely each variable relates to one another.For example, if you have a dataset relating to healthy children in middle school, height and weight will most likely have a high correlation. On the other hand, variables like height and favorite color probably won't have a high correlation. Under regression models, the computation and interpretation of the correlation coefficient is extremely important.The most common table looks like this, and is called a Product Pearson Correlation Table:Correlation tables can be straightforward when you master how to interpret and analyze themThe numbers in the table represent the correlation coefficient, which is a  measure  of how strong the relationship is between the variables in the table. In order to calculate the correlation coefficient, the only factors you need are the sample standard deviation and the sample covariance.The standard deviation is the measure of how far your data is spread around the mean, not to be confused with the standard error, which is how far your data is spread around the mean based not around your sample data but off of the actual population.The covariance, on the other hand, is the measure of how two variables vary together, which is very dependent on your sample data. The covariance should not be confused with the variance, which only measures how one variable varies inside of a data set.The correlation coefficient interpretation follows three basic rules. The first is that the numbers along the diagonal should always be one. The diagonal represents the correlation between the the variable with itself, which should always be 1, or 100%. For example, when the correlation between the variable favorite color and the same variable is 100%.The second rule is that higher above 50% correlation s hould be considered a high correlation, while below 50% should be considered a weak correlation. In this example, while favorite color has only 4% correlation with weight, weight and height have a strong correlation of almost 90%.The third rule is, while correlations below 50% are normally considered weak, it doesn't mean they cannot be of interest to you. In this example, favorite color has a 57% correlation with gender. While this isn't too strong of a correlation relative to the table, it does signal towards differences in gender that might be worth while to investigate further.Question 3: How to Interpret Statistical TestsStatistics, as you may have noticed, relies heavily on the information you have already learned. Therefore, it is important to master the basics of statistics before you can begin to understand and practice statistical tests.The interpretation of statistical tests will be different depending on which test you are performing. The two most common tests you will l earn at the beginning of your statistics career are:Chi Square TestT-TestBoth tests involve hypothesis testing, which utilizes statistics to test whether variables within the data are related or not. A t-test compares the means of two variables and gives you insight on how these two variables are related.  For example, when comparing between a new drug and a placebo, the health scores of two groups of patients can be analyzed using a t-test.A chi-square test, on the other hand, can either be used to determine whether the distribution of the sample data matches to a population, or whether two variables in a contingency table are related to one another.The first test is called a chi-square goodness of fit test, while the other is called a chi-square test for independence. An example of a chi-square test for independence can be found when trying to see whether level of educated is related to marital status by comparing them withing a contingency table.If you're confused about what test to perform for your set of data, check this guide out!Get Extra Statistics HelpLuckily, there are many resources that can provide helpful tips and tutorials if you are struggling with statistics. These range from a wide variety of online platforms, such as Superprof and Khan Academy, to textbooks and other reading material. One great source for getting extra statistics help online is Wolfram Math and Statistics How To. Both online platforms not only lay out the mathematical components of statistical concepts, but also explain them in thorough detail.If you need further explanations, heading over to Youtube can be a life-saver. If you're looking for helpful video tutorials, it is often best to search the keywords of the statistics terms you are struggling with and browse to see which video has the best material. If you'd prefer for someone to explain it to you in person, in-person tutoring is a great option. The best way to take advantage of this is to not be afraid to ask your prof essor for some extra help. Everybody learns at a different pace and in different ways, so it is important to keep that in mind as you continue on through your statistics journey.
