Correct Option: A
To find the median, we first organise the data from the table:
| Scores | 3 | 6 | 5 | 2 |
| Frequency | 2 | 3 | 4 | 6 |
Listing all data points:
- 3 appears 2 times → 3, 3
- 6 appears 3 times → 6, 6, 6
- 5 appears 4 times → 5, 5, 5, 5
- 2 appears 6 times → 2, 2, 2, 2, 2, 2
Ordered list:
2, 2, 2, 2, 2, 2, 3, 3, 5, 5, 5, 5, 6, 6, 6
There are 15 values. The median is in position:
\[ \, \frac{15 + 1}{2} = 8 \, \]
The 8th value is 3.
