In a box plot, the median is represented by the line inside the box. From your description:
- The right side line is at 60.
- The left side of the box is at 70, and the right side of the box is at 80, indicating that the lower and upper quartiles (Q1 and Q3) are at these values.
- The right line (whisker) is between 90 and 100.
Typically, the median is indicated by a line within the box, so based on the information provided, we can infer the median value. However, you didn't specify the position of the median line within the box, so I can only say that:
If the median is not explicitly mentioned, it should typically fall between Q1 (70) and Q3 (80). If the median is exactly centered, it would be the average of 70 and 80:
\[ \text{Median} = \frac{70 + 80}{2} = 75 \]
If there is a specific placement of the median inside the box you've observed, that would determine its exact value. Please check if there is a line within the box plot itself that indicates the median.
