To cope with the realities of incidence rate and nonresponse, researchers should use:
A) the sample adjustment formula.
B) always increase their sample size by 10%.
C) restrict themselves to the calculated sample size from the confidence interval formula.
D) ensure the sample size is always above 500.
E) ensure p and q are always equal to 50%.

Question

Quizplus · Accepted Answer

The sample adjustment formula helps to adjust the sample size based on the expected incidence rate and the likelihood of nonresponse, which can improve the accuracy and representativeness of the sample. Simply increasing the sample size may not address these issues adequately, and restricting oneself to a calculated sample size may not take into account practical constraints or unique circumstances. Setting equal values for p and q may not reflect the actual distribution of the population being studied.
