John is interested in determining if a new teaching method, the involvement technique, is effective in teaching algebra to first graders.
John randomly samples six first graders from all first graders within the Lawrence City School System and individually teaches them algebra with the new method.
Next, the pupils complete an eight-item algebra test. Each item describes a problem and presents four possible answers to the problem.
The scores on each item are 1 or 0, where 1 indicates a correct response and 0 indicates a wrong response. The IBM® SPSS® data file contains six cases, each with eight item scores for the algebra test.
Conduct a one-sample t-test on the total scores.
