Question

5 mark for review which of the following is a benefit to using a random sample for an observational study? a the random sample allows for different treatments to be assigned. b a causal relationship can be determined. c the results of the observational study can be generalized to the population. d a random sample is the easiest method of data collection. e the distribution of the sample will match the distribution of the population.

Explanation:

In an observational study, a random sample helps in generalizing results to the population as it is representative. Assigning treatments is for experiments, causal relationships are hard - to - determine in observational studies, random sampling isn't always the easiest, and the sample distribution may not exactly match the population distribution.

Answer:

C. The results of the observational study can be generalized to the population.
