The table below gives the scores of a group of students in a Mathematical test….

The table below gives the scores of a group of students in a Mathematical test.
(begin{array}{c|c} Scores & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \ hline Frequency & 2 & 4 & 7 & 14 & 12 & 6 & 4 & 1end{array})
If the mode in m and the number of students who scored 4 or less is s. What is (s, m)?
  • A.
    (27, 4)
  • B.
    (14,4)
  • C.
    (13,4)
  • D.
    (4,4)
Correct Answer: Option A
Explanation

M = mode = the number having the highest frequency = 4
S = Number of students with 4 or less marks
= 14 + 7 + 4 + 2
= 27
∴ (M,S) = (27, 4)
