Which one of the following is false?
- A Mean deviation from the mean and the Mean deviation from the Median must always be equal.
- B The measure of variability which is a number independent of units, is called the coefficient of variation
- C The coefficient of variation is a relative measure of variation
- D Among two given data, the one having greater coefficient of variation is said to have more variability than the other.
Answer & Solution
Correct Answer
(A) Mean deviation from the mean and the Mean deviation from the Median must always be equal.
Step-by-step Solution
Detailed explanation
Since, mean and median of a given data can have the different values. \(\therefore \quad\) Mean deviation from the mean and mean deviation from the median might not be equal for some data.
