Correct Answer

✅ Option c — Mean deviation

All Options:

  • ARange
  • BS. D
  • CMean deviation
  • DQuartile deviation

Detailed Solution & Explanation

The mean deviation (M.D.) of a set of data is the arithmetic mean of the absolute values of the deviations of the observations from an average (Mean, Median, or Mode). Because it takes the absolute value of each deviation, it is explicitly based on absolute deviations. Standard deviation is based on squared deviations, and range is based only on extreme values. Hence, **Option C** is the correct answer.
