Question

A major approach to "confirming what the data reveal" is the calculation of

Answer 1

Answer:

D. confidence intervals for a population parameter.

Explanation:

Standard deviation is simply a measure of the amount of dispersion of a set of values from the mean, hence it is not used to confirm what the data reveal.

Stem-and-leaf plots simply shows the frequency with which a set of values occur and hence it is not used to confirm what the data reveal.

A measure of central tendency, also sometimes signifies mean, mode, and median simply represents the typical value or middle point of a set of data, and hence it is not used to confirm what the data reveal

Confidence intervals for a population parameter refers to the probability of population parameter falling between two set values for a certain proportion of times. With the presence of probability, this shows that it is used to confirm what the data reveals.
