An increase in the sample size has the effect of decreasing the sampling error if the:
A) actual sample deviation rate increases.
B) actual sample deviation rate does not increase.
C) number of deviations in the sample increases.
D) number of deviations in the sample does not increase.

Question

Quizplus · Accepted Answer

The sampling error is inversely proportional to the square root of the sample size. Hence, an increase in the sample size will decrease the sampling error, provided that the actual sample deviation rate remains the same. If the actual sample deviation rate increases or the number of deviations in the sample increases, it will not necessarily decrease the sampling error.
