in order to assess whether viewpoints on decriminalization of marijuana for medical purposes change with age, four groups of participants, ages 20, 30, 40, and 50, are asked whether they support this issue. what is one flaw of this design?
recruitment could be a challenge because people of different ages are difficult to sample
social or cultural factors may influence the results, not age
longitudinal research is time consuming
marijuana has already been decriminalized in some places
clear selection

Explanation:

The study compares different age groups (20, 30, 40, 50) on their views about marijuana decriminalization. The flaw is that social/cultural factors (e.g., different eras' norms) for each age group might affect responses, not just age. Recruitment difficulty isn't a design flaw (it's a practical issue), longitudinal research isn't used here (it's cross - sectional), and marijuana's legal status in some places is irrelevant to the design's flaw.

Answer:

B. Social or cultural factors may influence the results, not age
