  • DFrequency

Detailed Solution & Explanation

In statistics, a class interval is defined by two values: a lower limit and an upper limit. - The **Lower Limit** is the smallest data value that can belong to that class. - The **Upper Limit** is the largest data value that can belong to that class. - The difference between the upper limit and the lower limit (or between the corresponding upper and lower class boundaries) determines the width, size, or magnitude of the class. This difference is called the **Class Interval** (or class width/length). For example, for the class 10−20\displaystyle 10 - 20, the class interval is 20−10=10\displaystyle 20 - 10 = 10. This is represented by Option A. Hence, **Option A** is the correct answer.
