A market researcher wants views from exactly 50 customers and is told to interview 20 men and 30 women, choosing whichever people are most easily available in a shopping centre until each group is filled. Which sampling method is this?
This is quota sampling. The sample is built by filling fixed numbers from each group, here 20 men and 30 women, using whichever people are readily available rather than random selection, so it is a non-random method.
- AQuota samplingCorrect
- BStratified random sampling
- CCluster sampling
- DSystematic sampling
Explanation
The researcher fills preset quotas for each group by choosing convenient people, with no random selection. This is quota sampling. Stratified random sampling would select within each group using random methods.
Did you get it right without looking?
One question tells you little. A timed set on Sampling methods shows your real accuracy, how long you take and where you lose marks.
