Let's analyze the box-and-whisker plots to answer the questions:

1. **(a) Which class had the highest test score?**
   - **Class B** had the highest test score, as the upper whisker of Class B extends to around 95, which is higher than Class A's maximum score (approximately 90).

2. **(b) Which class had test scores with a larger interquartile range (IQR)?**
   - **Class A** had a larger interquartile range (IQR). The IQR is the difference between the third quartile (Q3) and the first quartile (Q1), representing the length of the box. Class A's box is longer than Class B's, indicating a larger IQR.

3. **(c) Which class had a higher median test score?**
   - **Class B** had a higher median test score. The median is represented by the line inside the box. The median line for Class B is higher (around 75) than Class A's (around 72).

4. **(d) Which class had a smaller range of test scores?**
   - **Class B** had a smaller range of test scores. The range is the difference between the maximum and minimum values (the ends of the whiskers). Class B's range (from about 60 to 95) is smaller than Class A's range (from about 55 to 90).

Here are 5 related questions:
1. How is the interquartile range (IQR) useful in analyzing data sets?
2. What is the significance of the median in a box-and-whisker plot?
3. How does the range differ from the IQR when interpreting data spread?
4. Can two data sets have the same median but different IQRs? Why?
5. How could outliers affect the interpretation of a box-and-whisker plot?

**Tip**: The IQR is a great way to measure data spread because it focuses on the middle 50% of the data, making it resistant to outliers.

Two English classes took a final exam. The box-and-whisker plots summarize the test scores for each class. Use the plots to answer the questions.

Compare test scores between two English classes using box-and-whisker plots. Analyze the highest score, median, interquartile range (IQR), and range of scores for each class.
