Which one of the following is false?

Options

  1. AMean deviation from the mean and the Mean deviation from the Median must always be equal.
  2. BThe measure of variability which is a number independent of units, is called the coefficient of variation
  3. CThe coefficient of variation is a relative measure of variation
  4. DAmong two given data, the one having greater coefficient of variation is said to have more variability than th

Correct answer

A. Mean deviation from the mean and the Mean deviation from the Median must always be equal.

Step-by-step solution

Since, mean and median of a given data can have the different values. Mean deviation from the mean and mean deviation from the median might not be equal for some data.
