An environmental scientist investigated the recovery times of injured hedgehogs under two different rehabilitation protocols: Protocol A (quiet enclosure with naturalistic stimuli) and Protocol B (standard veterinary holding cage). The recovery time, measured in days to reach a set mobility threshold, was recorded for a sample of hedgehogs under each protocol.
The table below shows the frequency distribution, median recovery times, and ranges for both groups:
| Recovery Time (days) | Frequency (Protocol A) | Frequency (Protocol B) |
|---|---|---|
| 5 | 2 | 0 |
| 6 | 4 | 1 |
| 7 | 6 | 2 |
| 8 | 7 | 4 |
| 9 | 5 | 7 |
| 10 | 3 | 8 |
| 11 | 2 | 5 |
| 12 | 1 | 3 |
| 13 | 0 | 1 |
| 14 | 0 | 1 |
| Median | 8 | 10 |
| Range | 7 | 8 |
Outline a conclusion that can be drawn from the data in this table. Refer to the median recovery times to support your answer.
