Quizplus · Accepted Answer

A case study is the least appropriate design for testing the relationship between cigarette advertising and cigarette smoking by teenagers because it focuses on a single case or a small group of cases, and it does not allow for generalization to a larger population. A case study may provide useful information about a particular individual or group, but it does not provide a representative sample or allow for statistical analysis of the relationship between variables. Panel, cross-sectional, and trend studies are all appropriate designs for studying this relationship because they involve larger samples, multiple measurements over time, and statistical analysis of correlations or causal relationships.
