Question

tina is inspecting 1000 units of a new product sent to her by her manufacturer for her retail store. she randomly selected to start at the 5th unit and then every 10th unit after that. what kind of sampling is tina using?
select the correct answer below:
stratified sampling
systematic sampling
cluster sampling
convenience sampling

Explanation:

Systematic sampling involves selecting elements from a population at regular intervals (a sampling interval) after a random starting point. Here, Tina starts at the 5th unit and then selects every 10th unit, which fits the definition of systematic sampling. Stratified sampling divides the population into groups (strata) and samples from each; cluster sampling divides into clusters and samples entire clusters; convenience sampling uses easily accessible elements. So the correct type is systematic sampling.

Answer:

B. Systematic sampling (assuming the option order is as given, with the second option being Systematic sampling)
