Question

in what situations is it helpful to use a sample of a population? mark all that apply.
□ if the population is very large
□ if the population is very small
□ if it would take a lot of time to survey the entire population
□ if it would require a lot of money to survey the entire population
□ if the population does not match the survey question

Explanation:

• If the population is very large: Surveying the entire large population is impractical, so a sample is helpful.
• If it would take a lot of time to survey the entire population: Using a sample saves time compared to surveying the whole population.
• If it would require a lot of money to survey the entire population: A sample is more cost - effective than surveying the entire population.
• If the population does not match the survey question: This is not a situation for using a sample. A sample should be representative of the population relevant to the survey question. If the population is small, surveying the entire population (census) is more appropriate as a sample may not be necessary.

Answer:

A. if the population is very large
C. if it would take a lot of time to survey the entire population
D. if it would require a lot of money to survey the entire population
