An Analysis of Variance yielded the following results:

F-Value: 12.5

P-Value: .0000

Using a significance level of .05 interpret the results.

1. The data provides strong evidence that test scores are related to study strategy indicating that not all of the means are the same: one or more pairs have a statistically significant difference.
2. The data provides strong evidence that test scores are related to study strategy in the following way: the self paced group significantly outperformed the course guided group and the course guided group in turn out-performed the control group.
3. The data do not provide sufficient evidence that test scores are related to study strategy indicating that all of the means are the same: none have a statistically significant difference.
