Answer: Median

## Explanation Measures of variability (also called measures of dispersion) describe how spread out or scattered the data points are in a dataset. The key measures of variability include: 1. **Variance** - Measures the average squared deviation from the mean 2. **Standard deviation** - The square root of variance, expressed in the same units as the data 3. **Range** - The difference between the maximum and minimum values 4. **Interquartile range (IQR)** - The range between the 25th and 75th percentiles 5. **Mean absolute deviation** - Average absolute deviation from the mean **Median**, on the other hand, is a **measure of central tendency**, not variability. Measures of central tendency describe the center or typical value of a dataset and include: - Mean (average) - Median (middle value) - Mode (most frequent value) The question asks for the measure that is NOT a measure of variability, and among the options, only Median belongs to the category of central tendency measures, making it the correct answer.
