When the measure of central tendency is available in the form of mean, which one of the following is the most reliable and accurate measure of variability?

Options

  1. ARange
  2. BMean deviation
  3. CStandard deviation
  4. DQuartile deviation

Correct answer

C. Standard deviation

Step-by-step solution

Coefficient of variation (C.V.) = S . D mean 100 We know that the series having greater C.V. is said to be more variable.
