Question on Box Whisker Plot

Topic : Box Whisker Plot

Question : Explain Box Whisker Plot for the given sequence of numbers.

4,6,7,9,15,18,20,23,27,31,33,35

Solution :

4,6,7,9,15,18,20,23,27,31,33,35

Minimum value = 4
Maximum value = 35
The middle numbers are 18 and 20

Let Q2 is the middle term of whole sequence is 18 and 20
=(18+20)/2 = 38/2 = 19

Q2 = 19

And Q1 = (7+9)/2 = 16/2

Q1 = 8

Also Q3 = (27+31)/2 = 58/2

Q3 = 29
