Question

for a certain frequency distribution the value of mean is 20 and mode is 11, find the value of median

Answer 1

Solution :

Given mean (x) = 20,

mode (z) = 11 ,

Let the median = m

mode = 3median - 2mean

=> 3median = z + 2x

=> 3median = 11 + 2×20

=> median = 51/3

= 17

Therefore ,

median (m) = 17

Answer 2

Answer:

Step-by-step explanation:

3 Median = Mode + 2 Mean

3 x = 11 + 2× 20

3x = 11 + 40

Median = 51 /3
