The only time the population size is important in the calculation of sample size is:
A) always; all formulas include N, a count of the total population
B) when the population is very, very large
C) when the population is not normal
D) when the level of accuracy needs to be less than plus or minus 5 percent
E) when the population is small, relative to the sample size

Question

Quizplus · Accepted Answer

When the population size is small relative to the sample size, it is important to account for the population size in the calculation of sample size as it can affect the representativeness and accuracy of the sample. However, when the population is very large, even a relatively small sample size can be representative and accurate, and thus the population size is less important in sample size calculations. Choice A is incorrect because not all formulas include N, and choice B is only partially correct as the population size can still be important for smaller sample sizes. Choice C and D are both incorrect as they do not address the specific relationship between population size and sample size calculations.
