If the mean of the data , is times , then the mean deviation of the data from its mean is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
We know that mean deviation for ungrouped data: For 'n' observation x1,x2…………..xn, the mean deviation about their mean x¯ is given by M.D=∑i=1nxi-x¯N. where N is the number of observations Now given data of numbers are…
