Essay

A researcher conducts a study to determine if the variable of test anxiety influences performance on the GRE verbal and quantitative tests. He uses a questionnaire to assess individuals' test anxiety and classifies participants as high test anxious (n = 20) or low test anxious (n = 20). He is also interested in knowing whether high or low test-anxious individuals' performance is different for the computerized version of the test compared to the paper-and-pencil version of the test. 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).
-Assuming equal numbers of participants in each condition,how many individuals will be in each independent groups condition?
