| III. Stratified Random Sampling | 3. Random selection of first and systematic of the rest |
| IV. Stratified Systematic Random Sampling | 4. Random choice of all items from each stratum |
Answer: D
The keyed matching is: simple random sampling with equal probability of each item in all trials (2), random sampling with equal probability of selection of an item in a trial (1), stratified random sampling with random choice of all items from each stratum (4), and stratified systematic random sampling with random selection of the first and systematic of the rest (3), giving 2 1 4 3, option D. The stratified systematic design picks the first item at random and the others at fixed intervals. Options A, B and C pair the stratified and systematic designs with the wrong description.
