Question

Quizplus · Accepted Answer

Blair's goal is to understand changes in academic performance over a long period of time as a result of the number of friends children have. This requires a longitudinal study, which follows the same group of individuals over a period of time, rather than examining different groups of children at one point in time (cross-sectional design). Blair is also interested in observing relationships between variables over time, rather than manipulating variables (experimental design). Therefore, a longitudinal, observational study would be the best choice for Blair.
