The mean deviation from the mean of the discrete data is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
We know that mean of the observation is given by ratio of sum of observation to number of observation, So, Mean =1+3+4+7+11+18+29+47+789=1989=22 Now the mean deviation from the mean of the discrete data 1,3,4,7,11,18,29,47,78 will be,…
