A psychologist observed 44 adults immediately after each was told that an answer in a problem-solving task was incorrect. Each adult's first response was placed in one category.
| First response | Frequency |
|---|---|
| Checks the previous step | 14 |
| Asks for a hint | 14 |
| Starts the problem again | 9 |
| Continues without changing the answer | 7 |
The psychologist wants to select the mean, median or mode and report a single typical first response.
Explain whether the psychologist can do this.
