What is the repeated measures variable? What are the levels?
A researcher conducts a study to determine if the variable of test anxiety influences performance on two types of GRE tests, the verbal and quantitative tests. He uses a questionnaire to assess individuals' test anxiety and classifies participants as high test anxious (n = 40) or low test anxious (n = 40). He is also interested in knowing whether high or low test-anxious individuals' performance is different for the computerized version of the two tests compared to the paper-and-pencil version of the tests. Within each anxiety group, he randomly assigns participants to either the computer version or the paper version of the GRE tests. Participants then complete both the verbal and quantitative tests of the GRE in the test version they've been assigned (computer or paper). Thus, each participant has two scores, a Verbal score and a Quantitative score.
The repeated measures variable is the GRE tests with two levels, Verbal and Quantitative.
