Marina's study illustrates an example of a(n)

D) regression study.

Question

Quizplus · Accepted Answer

Marina's study is a replication study because it is a repeat of a previous study that examined the same research question and manipulated the same independent variable (underlining of important terms) to examine its effects on learning from text. This type of study is important to strengthen the validity of the previous findings by confirming or refuting them. The other options (A, B, and D) do not accurately describe Marina's study.
