**ONE-WAY ANALYSIS OF VARIANCE**

This will bring you to a table containing 8 components.

We will now go through each component, filling in
the appropriate number using the data in this study.

1. **Test significance level,** Alpha (a)
is the probability of rejecting the null hypothesis of equal means
when it is true (the probability of a Type I error).

Suggestion: Enter 0.05, a frequent standard

Acceptable entries: 0.001 to 0.20

**For this example: Ball &
Blachman set a = .05. So type ".05"
in the first box.

2. **Number of groups**, G Specify the number of
independent groups of subjects to be studied.

Acceptable entries: 2 through 8

**For this example: There are
three groups, so type "3" in the box.
