If the data are moderately non-symmetrical, then which one of the following empirical relationships is correct?

Options

  1. A2 Standard deviation =5 Mean deviation
  2. B5 Standard deviation =2 Mean deviation
  3. C4 Standard deviation =5 Mean deviation
  4. D5 Standard deviation =4 Mean deviation

Correct answer

C. 4 Standard deviation =5 Mean deviation

Step-by-step solution

We know, 4 5 standard deviation = Mean deviation 4 standard deviation =5 mean deviation
