Question

in a study, the sample is chosen by testing every 100th quart of ice cream off the assembly line for taste and consistency
what is the sampling method?
○ systematic
○ convenience
○ simple random
○ stratified
○ cluster

Explanation:

• Systematic sampling: Involves selecting elements at regular intervals (in this case, every 100th quart).
• Convenience sampling: Selects easily accessible elements, which is not the case here.
• Simple random sampling: Each element has an equal chance of being selected randomly without a fixed interval.
• Stratified sampling: Divides the population into subgroups (strata) and samples from each.
• Cluster sampling: Divides the population into clusters and randomly selects some clusters to sample from.

Since the sample is chosen by a fixed interval (every 100th quart), it fits the definition of systematic sampling.

Answer:

Systematic
