What is the coefficient of mean deviation of 21,34,23,39 , 26,37,40,20,33,27 (taken from mean)?

Options

  1. A0.11
  2. B0.22
  3. C0.33
  4. D0.44

Correct answer

B. 0.22

Step-by-step solution

Here mean aligned & = 21+34+23+39+26+37+40+20+33+27 10 & = 300 10 30 aligned Mean deviation = |-9|+4+|-7|+9+|-4|+7+10+|-10|+3+|-3| 10 = 66 10 =6.6 Coefficient of mean deviation = Mean Deviation Mean
