Question

(v) Find the median of the calls received on 7 consecutive days 11, 13, 17, 13, 23, 25, 19.

Answer 1

total no of elements = 7

median = n+1/2

7+1/2

8/2

4

hence median = 4

Answer 2

Concept

The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory. It might be regarded as "the midway" value for a set of data.

Given

The calls received on 7 consecutive days 11, 13, 17, 13, 23, 25, 19 are given

Find

We have to find the median of the calls received on 7 consecutive days

Solution

The steps are as follow:

• To find median first we have to arrange data in increasing or decreasing order here we will arrange data in increasing order as follow:

11,13,13,17,19,23,25

• Here n is number of given data which 7 i.e. odd
• So the formula for median will be as follow:

Median = M= (n+1)/2 th observation = (7+1)/2 th observartion

M = 8/2 th observation = 4th observation

M = 17

Hence the median of the calls received on 7 consecutive days will be 17
