Question

Quizplus · Accepted Answer

Dr. Ahmandi's study is a cross-sectional study because she compared the performance of two groups of children of different ages at one point in time. A longitudinal study would involve testing the same group of children over a period of time to see how their memory develops. A case study would involve an in-depth analysis of a single individual or a small group, and an experimental study would involve manipulating a variable to see its effects on memory.
