Detailed Solution & Explanation

In a frequency distribution table, each class is bounded by a lower limit and an upper limit. - The difference between the upper class limit and the lower class limit (or between the upper class boundary and the lower class boundary) determines the width or size of the class. - This difference is termed the **Class interval** (also referred to as class width or class length). - The mid-value is the average of the limits: Lower Limit+Upper Limit2\displaystyle \frac{\text{Lower Limit} + \text{Upper Limit}}{2}. - Class boundaries are the actual endpoints of the classes in continuous distributions. - Frequency is the number of observations in a class. Thus, the difference between the limits is the class interval. Hence, **Option A** is the correct answer.

Key Concepts to Understand

Limit

The value that a function f(x) approaches as the input x approaches a particular value. Written as lim(x→a) f(x) = L. It is the foundational concept of Calculus and is essential for defining derivatives and integrals.
