Step 1: Break Down the Problem

We need to identify which among the listed options is a measure of variability in statistics. The options provided are:

1. A) Mean
2. B) Mode
3. C) Median
4. D) Standard deviation

Step 2: Relevant Concepts

In statistics, measures of variability describe the spread or dispersion of a data set. The common measures of variability include:

• Range
• Variance
• Standard deviation The mean, mode, and median are measures of central tendency and do not describe variability.

Step 3: Analysis and Detail

1. Mean: The average of a data set.
2. Mode: The most frequently occurring value in a data set.
3. Median: The middle value when the data set is ordered.
4. Standard Deviation: A measure that quantifies the amount of variation or dispersion in a set of values. It indicates how much the individual data points deviate from the mean.

Step 4: Verify and Summarize

Among the options, the mean, mode, and median are measures of central tendency, while the standard deviation is the only measure of variability.

Final Answer

The measure of variability is D) Standard deviation.
