___________________ is sampling where a random sample at fixed periodic intervals is drawn from a large population?
Show answer Hide answer
Answer: D. Systematic sampling
Explanation
Systematic sampling is a probability method where researchers draw samples at fixed periodic intervals. Every kth element from a numbered population list is selected after choosing a random starting point. This technique ensures even geographic or chronological coverage across the entire study population. Probability sampling techniques allow researchers to calculate sampling error and generalize findings reliably. The sampling interval is calculated by dividing total population size by the desired sample size. Systematic sampling is often easier and faster to implement than simple random sampling methods.
Epidemiologists use systematic sampling to survey households along designated city streets efficiently. Quality control inspectors apply this method to select every tenth product off a manufacturing assembly line. Researchers must verify that population lists do not contain cyclical patterns before using this technique. Option A names cluster sampling where entire intact groups are randomly selected instead of individuals. Option B suggests stratified random sampling where populations are divided into distinct homogeneous subgroups. Option C proposes simple random sampling where every single member has an equal independent chance.
