ANOVA- October 11, 2012

This topic is our last one.
 And even though it is easy it is also a time consuming work to do.
You need to;

1st. State the Hypothesis and identify the claim.
2nd. Find the Critical Value.
3rd. Compute the test value: get the mean and variance of each sample, find the grand mean.
4th. Find the between group variance and within group variance.
5th. Find F-test value.
6th. Make the decision.
7th. Summarize the result.
8th. Plot the summary table for ANOVA.

and also there are tests like Scheffe Test and Tukey test that you need to do if your decision is to reject the null hypothesis.
And  scheffe tests will be long if you have many variables.
It is a great topic to learn because we can use it in our Research proposals.
