Question

The score in Maths test (out of 25) of students is as follows: 19,25,23,20,9,20,15,10,5,16, 25, Find the Median of this data.​

Answer 1

Given the scores in mathematics test (out of 25) of 15 students is as follows

19,25,23,20,9,20,15,10,5,16,25,20,24,12,20

Mode means which observation is most frequently occurred

Here observe that 20 is most frequently occurred so mode is 20. __(1)

first of all average the data in ascending order

5,9,10,12,15,16,19,20,20,20,20,23,24,25,25

Here observe that no of observations (n)=15

So median is N+1th/2 term

Median= 15+1th/2 term

= 16th/2 term= 8th term

median =20 __(2)

from (1) & (2)

mode = median

(Both are same)
