Question

Quizplus · Accepted Answer

In this study, the interval between the matrix and the cue is being manipulated by the researcher, making it the independent variable. The proportion of letters recalled is the dependent variable. Therefore, choice B is the correct answer. Choices A and C are incorrect because the results would be graphed with the interval on the x-axis and the proportion of letters recalled on the y-axis, and the best performance was actually found for the shortest cue delays. Choice D is not provided in the passage and is therefore irrelevant.
