The modality, symmetry, and variability of the sampling distribution of the mean are defined by a statistical principle known as ______.
A) random sampling
B) ratio scale of measurement
C) standard error of the mean
D) central limit theorem

Question

Quizplus · Accepted Answer

The central limit theorem describes the properties of the sampling distribution of the mean, including its modality (usually normal), symmetry, and variability, which are measured by the standard error of the mean. Random sampling and ratio scale of measurement are important concepts in statistics but not directly related to the sampling distribution of the mean.
