### Transcription with Explanation

#### Histogram Description
- **Title**: Not provided. (Annotation reads "I am not a good drawer, sorry").
- **X-Axis**: Represents IQ ranges from 80 to 150, labeled in intervals of 10 (80, 90, 100, 110, 120, 130, 140, 150).
- **Y-Axis**: Represents frequency, numbered from 0 to 10.
- **Data Bars**:
  - IQ 80-90: Frequency 3
  - IQ 90-100: Frequency 5
  - IQ 100-110: Frequency 7
  - IQ 110-120: Frequency 9
  - IQ 120-130: Frequency 8
  - IQ 130-140: Frequency 6
  - IQ 140-150: Frequency 1

#### Questions and Answers

**F. How many classes (a.k.a. bars) does this histogram have for the IQ data?**  
There are 7 classes in this histogram.

**G. What is the class width?**  
The class width is 10.

**H. Which class has the greatest number of students in it?**  
The class with the range 110-120 has the greatest number of students, with a frequency of 9.

**I. How would you describe the shape of the distribution?**  
The shape of the distribution is approximately normal, with the highest frequency in the middle class and tapering off on both ends.

**J. What are the differences between a Bar Graph and a Histogram?**  
“A Histogram Represents a quantitative variable and a Bar Graph Represents a categorical variable.”

### Additional Notes:
- A histogram is useful for displaying the frequency distribution of a set of continuous data points.
- The difference between a bar graph and a histogram is that bar graphs compare different categories, while histograms display the distribution of continuous data.

This transcription serves to help understand how histograms are used and interpreted in a statistical context.
