The table shown gives the marks scored by a group of student in a test. Use the table to answer the question given.
Mark | 0 | 1 | 2 | 3 | 4 | 5 |
Frequency | 1 | 2 | 7 | 5 | 4 | 3 |
What is the median mark?
1
2
3
4
Correct answer is C
Total frequency = 1 + 2 + 7 + 5 + 4 + 3 = 22
Median is the middle number
= \(\frac{Nth}{2}\)
term = \(\frac{22th}{2}\) = 11th term
Going in ascending order, 11th term is 3, going in descending order 11th term is 3
Median = 3 + \(\frac{3}{2}\) = \(\frac{6}{2}\) = 3
Answer is C
