Draw a box plot for the data set with the statistics in the picture
### Creating a Box Plot

To draw a box plot for the given data set, use the following statistics:

- **Minimum value:** 25
- **Maximum value:** 90
- **1st quartile (Q1):** 25
- **2nd quartile (Q2 or Median):** 50
- **3rd quartile (Q3):** 75

### Explanation:

1. **Box Plot Components:**
   - The left whisker starts at the minimum value (25).
   - The box begins at Q1 (25), covers the interquartile range, and ends at Q3 (75).
   - The line inside the box marks the median (Q2), which is 50.
   - The right whisker extends from Q3 (75) to the maximum value (90).

2. **Interpreting the Box Plot:**
   - The box plot visualizes the distribution of the data set.
   - The equal values of the minimum and Q1 indicate that the lower 25% of data points are clustered at 25.
   - The median (50) is closer to Q1, indicating a left-skewed distribution.
   - The range between Q1 and Q3 (the interquartile range) is 50, highlighting the middle 50% of the data. 

This box plot provides a quick graphical summary of the data through its spread and variations.
