AScore of 8
BScore of 10
CScore of 7
DScore of 9
Answer & Solution
Correct answer: D. Score of 9
1. The mode is the value that appears most often in the data.
2. Count the appearances: 7 once, 8 twice, 9 three times, 10 once.
3. The score 9 has the highest frequency, so the mode is 9.
4. Option A, 8, is the runner-up frequency, not the most frequent value.
