Question

a student scored the following marks in 11 questions of a question paper: 7, 3, 4, 1, 5, 8, 2, 2, 5, 7, 6. Find the median marks

Answer 1

Answer:

first of all arrange the numbers in asending order

Step-by-step explanation:

• 1,2,2,3,4,5,5,6,7,7,8. then there are total 11 numbers which is odd. so the median is the middle numbers which is =5

Answer 2

The median marks is 5.

Step-by-step explanation:

We are given the following in the question:

7, 3, 4, 1, 5, 8, 2, 2, 5, 7, 6

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Here the sample size is 11, which is odd.

Sorted data: 1, 2, 2, 3, 4, 5, 5, 6, 7, 7, 8

$\text{Median} = \dfrac{11+1}{1}^{th}\text{ term} = 6^{th}\text{ term} = 5$

Thus, the median marks is 5.
