Question

Refer to the previous question.

Consider the four options from Question 2 that could be a good choice for Cal Amity's survey. Then, select the one that you think would work most effectively in this situation. Lastly, describe in detail how you would select the individuals in the survey sample. (Include details such as how you might split the population into groups and/or what process you would use to make sure the survey respondents are chosen randomly, etc.) Support your choice of a random sampling method by explaining why it would be most effective in reducing bias.

The previous question:Which type of sample would not be a good choice for Cal Amity's survey, because it is known to cause bias?

a convenience sample
a stratified sample
a systematic sample
a simple random sample
a cluster sample

Answer 1

The correct approach is "a simple random sample".

Explanation:

• A simple random sample will become more efficient throughout this scenario because a sample of individuals becomes randomly generated from some kind of community so each individual has the same likelihood of someone being picked.
• This would contribute to the unpredictability as well as freedom of the experiments.

Some other four approaches do never use any of certain characteristics. So that is indeed the best decision.
