A researcher obtains the complete list of Grade 9 learners in a district and uses a random-number generator to select 300 names. Which sampling method is being used?

Correct answer: Simple random sampling Randomly selecting names from the complete list of the population is simple random sampling.

• Stratified random sampling Stratified sampling first divides the population into subgroups.
• One-stage cluster sampling Cluster sampling selects whole groups, not individuals.
• Systematic random sampling Systematic sampling selects at a fixed interval from the list.
