Question

if the first quartile (q1) is 25 and the third quartile (q3) is 75, what is the iqr?
a. 50
b. 75
c. 25
d. 100

Explanation:

Step1: Recall the formula for IQR

The formula for the inter - quartile range (IQR) is \(IQR = Q3 - Q1\).

Step2: Substitute the given values

Given \(Q1 = 25\) and \(Q3 = 75\), we substitute these into the formula: \(IQR=75 - 25\).

Step3: Calculate the result

\(75-25 = 50\).

Answer:

A. 50
