Answer

Explanation:

Step1: Sort the data

$[5,7,13,15,20,25]$

Step2: Find the median

Since $n = 6$ (even), median is average of 3rd and 4th values. Median$=\frac{13 + 15}{2}=14$

Step3: Find Q1

Lower - half is $[5,7,13]$, Q1 is the middle value of lower - half, so Q1 = 7

Step4: Find Q3

Upper - half is $[15,20,25]$, Q3 is the middle value of upper - half, so Q3 = 20

Step5: Calculate IQR

IQR=Q3 - Q1, so IQR = 20 - 7=13

Answer:

IQR: 13 Median: 14 Q1: 7 Q3: 20
