Weinstein, McDermott, and Roediger (2010) conducted an experiment to evaluate the effectiveness of different study strategies. One part of the study asked students to prepare for a test by reading a passage. In one condition, students generated and answered questions after reading the passage. In a second condition, students simply read the passage a second time. All students were then given a test on the passage material and the researchers recorded the number of correct answers.
a. Identify the dependent variable for this study.
b. Is the dependent variable discrete or continuous?
c. What scale of measurement (nominal, ordinal, interval, or ratio) is used to measure the dependent variable?
