Question

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? Select one:
a. Longitudinal research is time-consuming.
b. Marijuana has already been decriminalized in some places.
c. Recruitment could be a challenge because people of different ages are difficult to sample.
d. Social or cultural factors may influence the results, not age.

Answer 1

Answer:

One flaw of this design is 'Social or cultural factors may influence the results, not age'.

Explanation:

• There needs to be more criteria than just age. People of all ages engage in smoking so that should have been established prior to choosing.

• For any research, there need to be more deciding variables to obtain a more accurate result.

• So, more background is needed like culture and income level and race so that one set criteria can be chosen as deciding factor in opinion difference.

• So, social and cultural factors need to be taken into account to influence the results, not just age.
