Question

median of data 27,39,30,25,36,31,32,40is 30.5 if 27 is replaced by 45 then find the new median​

Answer 1

Step-by-step explanation:

First arrange the data in ascending order

25,27,30,31,32,36,39,40

Then count the number of observations,

count = 8

The count is even. So pick 31 and 32 and divide their sum by 2 to get the median.

median=30.5 (Given)

If 27 is replaced by 45, the data would be,

39,30,25,36,31,32,40,45

count = 8

median = (36+31)/2 = 67/2 = 33.5
