Question

certain distribution the value of mean is 21 ,mode is 18 . find the value of median

Answer 1

Heya,

Given:
Mean = 21
Mode =18

Empirical relationship between mean, mode and median is;

Mode = 3 Median - 2Mean
18 = 3 Median - 2(21)
3 Median = 18 + 42
Median = 60/3
Median = 20. ..... Answer

Hope this helps you....:)
Have a good day .....

Answer 2

given,
mean = 21
mode = 18

and, we know that,

2mean = 3 median - mode

so, 2× 21 = 3× median - 18
=> 42+18 = 3× median
=> 60 /3 = median
=> 20 = median
or Median = 20
