In a frequency distribution, **class limits** represent the smallest and largest data values that can belong to each class.

Each class in a frequency distribution has a lower class limit and an upper class limit:

**Lower class limit:**The smallest data value that can belong to a class.**Upper class limit:**The largest data value that can belong to a class.

The following examples show how to find class limits for different frequency distributions.

**Example 1: Finding Class Limits in a Frequency Distribution**

Suppose we have the following frequency distribution that represents the number of wins by different basketball teams:

The **lower class limit** is simply the smallest possible value in each class:

Conversely, the **upper class limit** is the largest possible value in each class:

**Example 2: Finding Class Limits in a Frequency Distribution**

Suppose we have the following frequency distribution:

The **lower class limit** is the smallest possible value in each class:

And the **upper class limit** is the largest possible value in each class:
