If is the mean of observations then the mean of the absolute deviations of these observations from is
- A the variance of the data
- B the mean proportion of the data
- C the standard deviation of the data
- D the mean deviation of the data
Answer & Solution
Correct Answer
(D) the mean deviation of the data
Step-by-step Solution
Detailed explanation
If x¯ is the mean of n observations x1,x2,…,xn then the mean of the absolute deviations of these observations from x¯ is the mean deviation of the data. Here, x¯=x1+x2+...+xnn ....1 Mean deviation =x1-x¯+x2-x¯+...+xn-x¯n
