In which sampling method is the same number of units chosen from each subgroup, regardless of the subgroup's proportion in the overall population?
A
Simple random sampling
B
Stratified random sampling
C
Proportionate stratified random sampling
D
Disproportionate stratified random sampling
Correct Answer:
D
Disproportionate stratified random sampling
- In disproportionate stratified random sampling, equal numbers of units are selected from each subgroup (stratum).
- The selection is independent of the subgroup’s actual proportion in the total population.
- This ensures adequate representation of smaller or minority groups.
- Useful when some strata are too small and may be overlooked in proportionate sampling.
- Contrasts with proportionate stratified sampling, where sample size matches population share.
- Example: Selecting 50 respondents each from rural and urban groups, even if their population sizes differ.
- Helps in comparative analysis between subgroups.
- However, it may require weighting during analysis to avoid bias.
- Widely used in social research where subgroup comparison is important.
