The question asks for the frequency of the class containing the value 2, based on the provided histogram.

From the histogram:

• The first class interval appears to cover values from approximately 1 to 5.
• The frequency for this class interval (from 1 to 5) is 2, as indicated on the vertical axis of the histogram.

Therefore, the frequency of the class containing the value 2 is 2.

Would you like further explanation or details?

Here are five related questions to deepen your understanding:

1. What is a histogram, and how do we interpret its different parts?
2. How can you determine the frequency of any class interval from a histogram?
3. What are the advantages of using histograms over other data visualization techniques?
4. How would you construct a histogram from raw data?
5. What are class intervals, and how are they typically determined in a histogram?

Tip: Always pay attention to the horizontal axis of a histogram, as it defines the range of values (class intervals) represented by the bars.
