90 47 88 53 59 72 68 62 79
Find minimum , first quartile , median , third quartile , and maximum of the given data set.
Answer to Problem 6P
Minimum = 47
First quartile = 56
Median = 68
Third quartile = 83.5
Maximum = 90
Explanation of Solution
Given:
90 , 47 , 88 , 53 , 59 , 72 , 68 , 62 , 79
Calculation:
Arrange the data in ascending order:
47 , 53 , 59 , 62 , 68 , 72 , 79 , 88 , 90
The minimum is 47.
The first quartile is the median of the lower half of the data set.
Since the total entries are 9, which is odd , So, the lower half is the first
So , the first quartile is
Median = The middle entry since there are 9 entries , which is odd =
The third quartile is the median of the upper half of the data set.
Since the total entries are 9, which is odd , So, the upper half is the last
So , the third quartile is
The maximum is 90
