Question

since 15 percent of a university is comprised of asian-american students, a sample for a study was chosen in such a way that it, too, consisted of 15 percent asian americans. this kind of sample would be an example of a ______.

○ crowd sample

○ random sample

○ static sample

○ stratified sample

Explanation:

To solve this, we analyze each option:

• Crowd sample: Not a standard sampling term in this context.
• Random sample: Involves randomly selecting individuals, not matching population proportions.
• Static sample: Not a recognized sampling method for this scenario.
• Stratified sample: Involves dividing the population into strata (e.g., by ethnicity) and sampling to match the population's proportion of each stratum. Here, the sample matches the university's 15% Asian - American proportion, so it's a stratified sample.

Answer:

D. stratified sample
