we will be assuming that the variances are equal. Ignore the Levene's Test for Equality of Variances.

The result of the analysis is t ( ? ) = , p =

The result of the analysis is t ( ) = ? , p =

The result of the analysis is t ( ) = , p = 0.029

One-tailed Analyses

Let's also look at how to analyze the data if you were to perform a one-tailed test to test a theory which predicts that the activities should lead to an increase in performance scores.

What would be the one-tailed p value? p=___________

Round to the nearest thousandths place for this question.

Next let's look at how to analyze the data if you were to perform a one-tailed test to test a theory which predicts that the activities should lead to a decrease in performance scores.

Did the sample means go in the direction predicted by the theory?

What would be the one-tailed p value? p=___________

Round to the nearest thousandths place for this question.
