Question Analysis
This question assesses the student's understanding of how to calculate the Interquartile Range (IQR) from a given data set. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).

Key Concept Explanation
The Interquartile Range (IQR) is a measure of statistical dispersion, representing the range covered by the middle 50% of the data. It is calculated as IQR = Q3 - Q1.

Step-by-step Solution
1. First, sort the data set: 10, 14, 16, 18, 20, 22, 24, 26 (already sorted).
2. Determine the median (Q2): The median is the average of 18 and 20, which is 19.
