You know that iPhone users outnumber Android users 10 to 1 in your population. In order to be able to make meaningful comparisons between the two groups of phone users, which sampling method is most appropriate?
Disproportionate Stratified
sample Simple Random
Sample Systematic Sample
Proportionate Stratified Sample
Homework Answers
Option d: Proportionate Stratified Sample is correct
Since the population consists of two different stratas whose distribution is quite different and the proportion is known, hence we would construct the two stratas and then take the sample according to proportions.

Would you agree to the statement on random sampling methods. Please explain why. In probability samples “each population element has a known (non-zero) chance of being chosen for the sample.” (StatTrek 2020). Some examples of probability samples are, simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling. Simple random sampling is the population and sample consists of “N” objects, and an example is when people play the lottery. Stratified sampling is based on some type of...
