338 390 414 260 110 108 398 203

Explanation:

Step1: Recall the formula for IQR

The inter - quartile range \(IQR = Q_{3}-Q_{1}\).

Step2: Substitute the values of \(Q_{3}\) and \(Q_{1}\)

Given \(Q_{1}=156.5\) and \(Q_{3}=394.0\). Then \(IQR=394.0 - 156.5\).

Step3: Calculate the result

\(IQR=394.0-156.5 = 237.5\)

Answer:

\(237.5\)
