Question

question 1 / 2 which sampling method selects items at intervals from a production ss? a. a. random sampling b. b. cluster sampling c. c. systematic sampling d. d. stratified sampling

Explanation:

To determine the sampling method that selects items at intervals from a production process, we analyze each option:

• Option A (Random sampling): Involves selecting items randomly without any fixed interval. So, this is not correct.
• Option B (Cluster sampling): Divides the population into clusters and then samples entire clusters. There's no fixed interval involved in the selection of items from the production process, so this is incorrect.
• Option C (Systematic sampling): In this method, after a random start, items are selected at regular (fixed) intervals from the population (in this case, the production process). This matches the description of selecting items at intervals.
• Option D (Stratified sampling): Divides the population into strata (sub - groups) and then samples from each stratum. It does not involve selecting items at intervals from the production process, so this is incorrect.

Answer:

C. Systematic sampling
