Which sampling method ensures that every member of the population has an EQUAL and INDEPENDENT chance of selection?

• A Stratified random sampling
• B Cluster sampling
• C Simple random sampling ✓
• D Systematic random sampling

Explanation

Simple random sampling gives every individual in the population an equal and independent probability of selection. Stratified sampling divides into strata then samples randomly; cluster sampling selects groups not individuals; systematic sampling selects every nth person, so choices are not fully independent once the first is chosen.
