Take the first class interval, say \(15 - 20\). The lower limit is \(15\) and the upper limit is \(20\).

Step2: Calculate class width

Class width is the difference between the upper limit and the lower limit of a class. So, \(20 - 15 = 5\). We can check with another class, e.g., \(21 - 26\), \(26 - 21 = 5\), which confirms the class width.
