In histograms, width of the bars is determined by class size. (True/False)

Answer

To determine whether the statement "In histograms, width of the bars is determined by class size" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components of a Histogram**:
- A histogram is a graphical representation of the distribution of numerical data.
- It consists of bars where the height of each bar represents the frequency of data points within a certain range (class interval).

2. **Identify Class Intervals**:
- Class intervals are the ranges of values that data points fall into. For example, if we have class intervals like 3-5, 6-8, and 9-11, these intervals help categorize the data.

3. **Determine Class Size**:
- Class size is calculated as the difference between the upper limit and the lower limit of a class interval. For example, for the class interval 3-5:
- Class size = Upper limit - Lower limit = 5 - 3 = 2.
- This means that the width of the bar representing this class interval in the histogram will also be 2.

4. **Relate Width of Bars to Class Size**:
- The width of each bar in a histogram corresponds directly to the class size. Therefore, if the class size is 2, the width of the bar for that interval will also be 2.

5. **Conclusion**:
- Since the width of the bars in a histogram is indeed determined by the class size, we can conclude that the statement is true.

### Final Answer:
The statement "In histograms, width of the bars is determined by class size" is **True**.
