The difference between upper limit and lower limit of the class interval in called as:

Options

A. range
B. mode
C. Frequency distribution
D. class size

Answer

To solve the question, we need to identify the term that describes the difference between the upper limit and lower limit of a class interval in statistics.

### Step-by-Step Solution:

1. **Understanding Class Intervals**:
- A class interval is a range of values that is used to group data. Each class interval has an upper limit and a lower limit.

2. **Identifying Upper and Lower Limits**:
- The upper limit is the highest value in the class interval, while the lower limit is the lowest value.

3. **Calculating the Difference**:
- The difference between the upper limit and lower limit can be calculated using the formula:
\[ \text{Difference} = \text{Upper Limit} - \text{Lower Limit} \]

4. **Defining the Term**:
- The term used to describe this difference is known as the "class size." This term indicates the width of the class interval.

5. **Selecting the Correct Option**:
- From the options provided (range, mode, frequency size, class size), the correct answer is "class size."

### Final Answer:
The difference between the upper limit and lower limit of the class interval is called **class size**.
