Question

Quizplus · Accepted Answer

Dr. Smith is conducting a cross-sectional study by comparing the intelligence of participants from different age groups on the same date. A longitudinal study would require following the same group of participants over a period of time, while a correlational study would involve analyzing the relationship between two variables. Naturalistic observation involves observing behavior in a natural setting, which is not what Dr. Smith is doing in this study.
