## Residual Mean Square

a one-way ANOVA. In Lesson 9 you learned how to compare the means of two independent groups. In this lesson, we will learn how to compare the means of more than two https://onlinecourses.science.psu.edu/stat200/book/export/html/66 independent groups. This procedure is known as a one-way analysis of variance, or more http://www.biostathandbook.com/standarderror.html often as a "one-way ANOVA."Why not multiple independent t tests?A frequently asked question is, "why not just perform multiple t tests?" If you were to perform multiple independent t tests instead of a one-way ANOVA you would need to perform more tests. For $$k$$ independent groups there are $$\frac{k(k-1)}{2}$$ possible pairs. If you had standard deviation 5 independent groups, that would equal $$\frac{5(5-1)}{2}=10$$ independent t tests! And, those 10 independent t tests would not give you information about the independent variable overall. Most importantly, multiple t tests would lead to a greater chance of making a Type I error. By using an ANOVA, you avoid inflating $$\alpha$$ and you avoid increasing the likelihood of a Type I error. 10.1 - Introduction to the F standard error anova Distribution One-way ANOVAs, along with a number of statistical tests, rely on the F distribution. Earlier in this course you learned about the z and t distributions. You computed z and t test statistics and used those values to look up p-values using statistical software. Similarly, in this lesson you are going to compute F test statistics. The F test statistic can be used to determine the p-value for a one-way ANOVA. The video below gives a brief introduction to the F distribution and walks you through two examples of using Minitab Express to find the p-values for given F test statistics.Using Minitab and Minitab Express to Find the Area Under the F DistributionThe steps for creating a distribution plot to find the area under the F distribution are the same as the steps for finding the area under the z or t distribution. Remember though that for the F distribution we will always be looking for the right-tailed probability. Later in this lesson we will see that this area is the p-value.Minitab Express MacStatistics > Probability Distributions > Distribution Plot > Display ProbabilityMinitab Express PCSTATISTICS > Distribution Plot > Display ProbabilityMinitab 17Graph > Probability Distribution Plot > View ProbabilityThe video above

Introduction When you take a sample of observations from a population and calculate the sample mean, you are estimating of the parametric mean, or mean of all of the individuals in the population. Your sample mean won't be exactly equal to the parametric mean that you're trying to estimate, and you'd like to have an idea of how close your sample mean is likely to be. If your sample size is small, your estimate of the mean won't be as good as an estimate based on a larger sample size. Here are 10 random samples from a simulated data set with a true (parametric) mean of 5. The X's represent the individual observations, the red circles are the sample means, and the blue line is the parametric mean. Individual observations (X's) and means (red dots) for random samples from a population with a parametric mean of 5 (horizontal line). Individual observations (X's) and means (circles) for random samples from a population with a parametric mean of 5 (horizontal line). As you can see, with a sample size of only 3, some of the sample means aren't very close to the parametric mean. The first sample happened to be three observations that were all greater than 5, so the sample mean is too high. The second sample has three observations that were less than 5, so the sample mean is too low. With 20 observations per sample, the sample means are generally closer to the parametric mean. Once
