The image shows a box-and-whisker plot, which provides key data points for statistical analysis. From the plot, we can observe the following information:

- **Minimum value**: 0
- **Q1 (first quartile)**: 25
- **Median (Q2)**: 49
- **Q3 (third quartile)**: 57
- **Maximum value**: 78

### Answers to the questions:

1. **Median**: The overall median of the data is represented by \( Q_2 \), which is clearly marked as **49**.

2. **Group separator**: The number separating the first and second groups refers to \( Q_1 \), the first quartile, which is **25**.

Thus:

- **Median = 49**
- **Group Separator = 25**

Here are 5 related questions for further practice:

1. How is the interquartile range (IQR) calculated from the box-and-whisker plot?
2. What does it mean if a box-and-whisker plot is skewed to one side?
3. How do you calculate the range of the data set based on this plot?
4. What percentage of data lies between the first and third quartiles?
5. How would outliers be represented in a box-and-whisker plot?

**Tip**: The interquartile range (IQR) is a key measure of variability and is the difference between \( Q_3 \) and \( Q_1 \).

What is the overall median of the data? What number separates the first and second groups?

Learn how to find the median (Q2) and the group separator (Q1) from a box-and-whisker plot. This example uses data with a median of 49 and a group separator at 25. Suitable for students in Grades 6-8.
