Answer: order of test items
Explanation: An independent variable is a variable that is specifically manipulated by a researcher to investigate whether it consequently brings about change in another variable. The other variable, which is measured and predicted to be dependent upon the independent variable, is known as the dependent variable.
In the experiment above, the independent variable is the order or arrangement of the test items. The instructor gave two sets of order to two groups of students to study effect of the order on test scores. The effect on the test scores may be dependent on the order the tests were arranged.
