Which of the following is not a measure of variability?

Question

BlackTom AI · Accepted Answer

Examining the question: 'Which of the following is not a measure of variability?'

First, note that the provided data lacks any answer choices. The field for answer_options is empty, so we cannot evaluate each option individually.

In general, to identify a non-variability measure, we would compare possible options against common measures of variability such as: range, variance, standard deviation, and interquartile range. These are all statistics that describe how spread out the data are.

As for the given answer hint 'c. The mean.': the mean is a measure of central tendency, not variability. It tells us the central value of the data, not how spread out the data points are. If this were presented as an option among the choices, it would be a valid statement that the mean is not a measure of variability, though we cannot confirm its status among the actual options since they are missing.

Because no concrete options are provided, we cannot systematically analyze why each listed choice is correct or incorrect. The lack of listed options prevents a step-by-step comparison of each candidate measure (range, variance, standard deviation, IQR, etc.) versus the mean or other potential contenders.

In summary, conceptually, the mean is not a measure of variability, but to complete the exercise as intended, the actual set of answer options would need to be supplied so we can evaluate each one individually and explain why it does or does not quantify dispersion.
