Question

For a study on the health problems of drug users, a random sample of New York City high school students is drawn. A low level of health problems is found. Jim argues that the findings are generalizable because they were based on a random sample. Meagan argues that the findings are not generalizable because they reflect only high school students in New York City. How would you evaluate their positions?a. neither claim can be correct since prescription drug use cannot be generalized to any population.

b. only jim is correct because he is referring to sample generalizability.
c. only meagan is correct because she is referring to cross-population generalizability.
d. both claims concerning sample and cross-population generalizability are correct.

Answer 1

Option D

Explanation:

it is good for generalization for groups that have to do with high School students because the certainty of results of the study sample represents the results that would be obtained for the entire population of new York high school students. It can or represent a cross population generalization because the group does not include any student from other groups of the population of new York so it cannot be used to represent all the groups that come under the population of new York.

Answer 2

both claims concerning sample and cross-population generalizability are correct.

Explanation:

Both claims are correct because with a simple random sample you cannot conclude for the whole population.
