Mode: $25$
Which is the best measure that represents the data?

• A. Median
• B. Mean
• C. None of these
• D. Mode

Answer 1

The correct option is B Mean

The given data set is $21,21,21,23,23,24,24,24,25,25,25,25,26$.
The mean is $23.6$, the median is $24$, and the mode is $25$. Mean is the best measure that represents the data as the data set doesn’t contain any outliers, and mean is the only measure of the center that uses all the values of the data.
Option C is correct.
