B)develop an understanding of a phenomenon in terms of "if-then" conditional statements.
C)search for and interpret existing information relevant to the research problem.

Question

Quizplus · Accepted Answer

Longitudinal studies repeatedly measure the same sample units from the population over a period of time, allowing researchers to track changes and developments in the variables being studied over time. This is in contrast to cross-sectional studies, which measure the population at only one point in time. Option A is incorrect for this reason. Option B describes an experimental design that uses conditional statements, but is not specific to longitudinal studies. Option C describes a literature review, which is a different research method. Option E describes a comparative study, which is also a different method.
