To determine the number of values in the class range from 6 to 12, let’s analyze the bars on the histogram provided.

The class 6 - 12 includes the two bars that span from approximately 6 to just before 12. Observing the heights of these bars:

• The bar from 6 to 8 has a height of 1.
• The bar from 8 to 10 has a height of 2.

Adding these heights, we get: $1 + 2 = 3$

Therefore, there are 3 values in the class range 6 - 12.

1. How do you determine class intervals in a histogram?
2. What does the height of a bar in a histogram represent?
3. How can you calculate the total number of values represented in a histogram?
4. Why is the histogram divided into class intervals?
5. How does the color of bars help in interpreting a histogram?

Tip: When interpreting a histogram, always verify both the range of each class interval and the height of the bars for accurate data counting.
