Question

98, 64, 75, 57, 86, 60, 91, 98, 79
Find the median
Find the median of the first
quartile
find the median of the third quartile
What is the inter quartile range

## Answers ( )

Answer:The median is

79The median of the first quartile is

62The median of the third quartile is

94.5The inter quartile range is

32.5Step-by-step explanation:The medianis the middle number of arranged number from smallest to greatestThe median of the first quartileis the middle number of the numbers before the medianThe median of the third quartileis the middle number of the numbers after the medianThe inter quartile rangeis the difference of the median of the 3rd quartile and the median of the 1st quartileThe numbers are 98, 64, 75, 57, 86, 60, 91, 98, 79

Let us arrange the numbers from small to big

57, 60, 64, 75, 79, 86, 91, 98, 98They are 9 numbers

The middle one is the

5thnumber (4 before it and 4 after it)The 5th number is

79The median is 79The numbers before the median are

57, 60, 64, 75They are 4 numbers

The middle numbers are 2nd and 3rd

The median is the average of them

The 2nd number is 60 and the 3rd number is 64

The median of the first quartile = = 62

The median of the first quartile is 62The numbers before the median are 86, 91, 98, 98

They are 4 numbers

The middle numbers are 2nd and 3rd

The median is the average of them

The 2nd number is 91 and the 3rd number is 98

The median of the third quartile = = 94.5

The median of the third quartile is 94.5The inter quartile range = third median – first median

First median = 62

Third median = 94.5

Inter quartile range = 94.5 – 62 = 32.5

The inter quartile range is 32.5
