Frequency distributions are most useful for determining the:
A. Standard deviation of a distribution
B. The median of a distribution
C. The variance of a distribution
D. The shape of the underlying distribution
Homework Answers
Frequency distributions are most useful for determining the "The Shape of the underlying distribution"
So Option D) is Correct.
Because, As we know Frequency distributions are also used to calculate the Std Deviation, Median and Variance, but the main aim of Frequency distributions is to show the Shape of Distribution.

Sampling Distributions Given a sampling distribution of means, how are the mean and standard deviation determined (calculated)? If an original sampling is not normal, how many must we sample to say it is approximately normal? Given a sampling distribution of proportions, how are the mean and standard deviation determined (calculated)?
