When we are working by hand with problems involving standard deviation, it is a good idea to break up our formula into steps and to create a table to aid us along the way. The following example will show you how to break your formula up and will give you a table to guide you along. Ex. A random sample of seven New York plays gave the following ...

Finally, because the F test is the variance between divided by the variance within, we get our F-ratio: F = MSbetween. MSwithin. So for the Alcohol study, F = 10.067/1.567 = 6.426. Finally, you should always present what is called an Anova Summary Table that contains the results of all of these calculations. It should look like: Source SS df MS F
