This image presents a box-and-whisker plot and asks two questions:

1. What is the overall median of the data?
2. What number separates the third and fourth groups?

To solve this:

1. Median of the data: The overall median is the median of the entire data set. From the box-and-whisker plot, we see that the median (Q2) is at 29.5. This is the value that divides the data set into two equal halves.

2. Separator between the third and fourth groups: The third and fourth groups are separated by Q3, the third quartile. From the plot, Q3 is located at 53.8.

So, the answers would be:

• Median: 29.5
• Group Separator: 53.8
