Correlated Samples t-test

We will use the data shown in this screen to illustrate the correlated samples t-test. We will use ONLY the 10- and 15-distracter conditions, because a correlated samples t-test can only compare two conditions at a time.

Note that the appropriate analysis for this entire data set would be a repeated measures ANOVA. However, we are using the first two variables solely for the purposes of illustrating how one should set up a correlated t-test.
