Which one of the following is not a measure of central tendency?
Show Hint
- Mean
- Median
- Mode
- Standard deviation
The Correct Option is D
Solution and Explanation
Step 1: Understand central tendency.
Central tendency is a statistical measure used to determine a single value that represents the center of a data set. The most common measures of central tendency are: \[ \text{Mean}, \text{Median}, \text{Mode} \]
Step 2: Standard deviation is not a measure of central tendency.
Standard deviation measures the spread or dispersion of data, not the center. Therefore, it is not considered a measure of central tendency.
Step 3: Conclusion.
Thus, the correct answer is (D) Standard deviation.

- The company at which Mark is employed has 80 employees, each of whom has a different salary. Mark’s salary of 43,700 is the second-highest salary in the first quartile of the 80 salaries. If the company were to hire 8 new employees at salaries that are less than the lowest of the 80 salaries, what would Mark’s salary be with respect to the quartiles of the 88 salaries at the company, assuming no other changes in the salaries?
