Question

the marks of 15 students in a examination are 25, 19, 17, 24, 23, 29, 31, 40, 19, 20, 22, 26, 17, 35, 21. Find the median score.​

Answer 1

Answer:

Median = 23

Step-by-step explanation:

Given in the question

Number of sample (n) = 15

First we will sort the data from smallest to largest data value as follows

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

We need to calculate median which can be calculated as

Median = (n+1)/2 = (15+1)/2 = 8th data value

from the sorted data set we found 8th value is 23

So Median = 23
