Question

Select the order of sampling schemes from best to worst.

a. simple random, stratified, convenience
b. simple random, convenience, stratified
c. stratified, simple random, convenience
d. stratified, convenience, simple random

Answer 1

The best to worst order of sampling schemes is stratified sampling, simple random sampling, and convenience sampling, respectively.

Step-by-step explanation:

The question asks to select the order of sampling schemes from best to worst in terms of efficacy in producing unbiased and representative samples. When we evaluate the different sampling methods, stratified sampling generally provides a highly representative sample because it ensures that all subgroups of the population are adequately represented. Simple random sampling also gives each individual an equal chance of being selected, which helps in avoiding bias. Lastly, convenience sampling often leads to biased data because it relies on samples that are easy to reach rather than being representative of the entire population.

Therefore, the correct order from best to worst would be:

1. Stratified Sampling
2. Simple Random Sampling
3. Convenience Sampling
