Which of the following is NOT a measure of central tendency?

• A. Mean
• B. Median
• C. Variance
• D. Mode

Answer: (C)

The measure identified as variance is not a measure of central tendency. Instead, variance is a statistical measure that indicates how much data points in a set deviate from the mean, providing insight into the distribution and spread of the data. It assesses the variability or dispersion of a set of values.

On the other hand, the mean, median, and mode are all measures of central tendency, which help to summarize a set of data by identifying the central point within that data. The mean is the average of all values, the median represents the middle value when data is arranged in order, and the mode indicates the most frequently occurring value in the dataset. These measures are fundamental in understanding the overall trend of a data set, while variance focuses on how much the data varies around that center.
