A researcher records how long five participants take to find a target letter hidden among distractor letters.
| Participant | Completion time (seconds) |
|---|---|
| A | 23 |
| B | 26 |
| C | 28 |
| D | 29 |
| E | 31 |
After the task, Participant A writes, "I scanned each line from left to right instead of looking around randomly."
Explain which measure of central tendency would give an appropriate summary of the completion times and what Participant A's account adds to the interpretation of the results.
