Question

The marks of 15 students (out of 50) in an examination are-
20, 22, 26, 31, 40, 19,17, 19, 25, 29,23, 17, 24, 21,35
Find the mode and median of this data.​

Answer 1

Step-by-step explanation:

hope this helps you mark as brilliant and follow me

Answer 2

Step-by-step explanation:

Mode = sum of all terms/No of terms

= 20+22+26+31+40+19+25+29+23+17+24+21+35/15

=368/15

=23.533

Median=

First we have arrange the given raw data in ascending order

Arranged data = 17, 17, 19, 19, 20, 21, 22, 23, 24, 25, 26, 29, 31, 35,40

for odd terms:

median =(n+1)/2th term

Here n= 15

So, median= (15+1)/2th term

=(16/2)th term

=8th term

= 23 (Ans)

Hope this helps you!
