Consider the following grouped frequency distribution :
Class0-1010-2020-3030-4040-5050-60
Frequency124643
What is mean deviation about the median?

Options

  1. A11.411.4
  2. B11.111.1
  3. C10.810.8
  4. D10.510.5

Correct answer

D. 10.510.5

Step-by-step solution


Meadian =∑∣xi−Me∣∑fi=21020=10.5=\frac{\sum\left|x_i-M_e\right|}{\sum f_i}=\frac{210}{20}=10.5
