Question

This box and whisker plot shows the time taken by two groups of students to solve a science problem

Answer 1

The bottom of the line is a Minimum, the bottom of the rectangle is the Lower-Quartile, the line inside the rectangle is the Median, the top of the rectangle is the Upper-Quartile, the top of the line is the maximum.
Here is what I estimate the values to be given the positions of the line (may be off by 3-4).
Group 1:
- Lower Quartile: 37
- Median: 41
- Upper Quartile: 50

Group 2:
- Lower Quartile: 60
- Median: 80
- Upper Quartile: 92

We can tell A and C are obviously wrong. I favor choice B over D because the Lower Quartile of Group 2 is closer to the 20s than 10s away from the Lower Quartile of Group 1.

Answer 2

I think D im not sure though <span />
