Question
Which of the following statements is true regarding sample size calculations?*1 pointA. Slovin's formula is used for determining the sample size for stratified sampling.B. Cochran's formula accounts for the margin of error and confidence level.C. Population size is not a consideration when calculating sample size.D. Slovin's formula is suitable for use in all types of sampling methods.
Solution
The true statement regarding sample size calculations is B. Cochran's formula accounts for the margin of error and confidence level.
Here's why:
A. Slovin's formula is not specifically used for determining the sample size for stratified sampling. It is a formula used when the population is large, and it is not specific to any type of sampling method.
B. Cochran's formula does indeed account for the margin of error and confidence level. It is a statistical technique used to determine the sample size required for a study, given a desired level of precision, desired confidence level, and the estimated proportion of the attribute present in the population.
C. Population size is a consideration when calculating sample size. In fact, it's one of the key factors that influence the size of the sample needed.
D. Slovin's formula is not suitable for use in all types of sampling methods. It is typically used when the population size is very large or unknown.
