Professor Testgiver wonders if the order in which questions are put on a test affects the test
Question:
Professor Testgiver wonders if the order in which questions are put on a test affects the test score. He administers different forms of the same test to three subsets of 10 students in his class. On one form, the more difficult questions are at the beginning and the easiest questions are at the end. In the next form, the easiest questions are at the beginning and the more difficult questions are at the end. In the third form, items are randomly placed, not in order of their difficulty. Here are the students’ test scores (out of 20):
a. What are the independent and dependent variables in this study?
b. State the null hypothesis and the research hypothesis.
c. Calculate F and compare it with the critical value of F at the .01 and .05 α levels. At what level of error can you reject the null hypothesis, if at all?
d. Write the results in APA journal format.
