here are the ages of 13 people in a coffee shop on a given day: 26, 44, 22, 28, 55, 32, 15, 39, 54, 69, 21, 18, 48 identify the third quartile by finding the middle number on the right side of the median. if there is no middle number, average the two middle numbers. 15, 18, 21, 22, 26, 28, 32, 39, 44, 48, 54, 55, 69 first quartile (q1) median (q2) third quartile (q3) 21.5 ?
Answer
Explanation:
Step1: Identify the data set on the right side of the median
The median is (32). The data set on the right side of the median is (39,44,48,54,55,69).
Step2: Calculate the third quartile
Since there are (6) numbers (an even count), we average the two middle numbers. The two middle numbers are the (3^{rd}) and (4^{th}) numbers in the ordered set (39,44,48,54,55,69). [ \frac{48 + 54}{2}=\frac{102}{2} = 51 ]
Answer:
(51)
