Question 1
Measures of Central TendencyScore: 1, 2, 3, 4, 5, 6, 7, 8
Frequency: 2, 3, 5, 12, 10, 6, 4, 1
The table above shows the scores of a group of students in a Physics test. If the mode is m and the number of students who scored 4 or more is n, what is (n, m)?
- A.(33, 4)
- B.(22, 4)
- C.(33, 12)
- D.(12, 4)
Show the answer and explanation
Answer: A ((33, 4))
Explanation
The highest frequency (12) is for score 4, so m = 4. Students scoring 4 or more: 12 + 10 + 6 + 4 + 1 = 33, so (n, m) = (33, 4).
