Step-by-step explanation:
Given Find the median for the data marks =20,29,28,33,42,38,43,25, Number of students = 6,28,24,15,2,4,1,20
- We need to find the median. So we need to arrange the data in ascending order so we get
- Marks obtained No of students Cumulative frequency
- 20 6 6
- 25 20 26
- 28 24 50
- 29 28 78
- 33 15 93
- 38 4 97
- 42 2 99
- 43 1 100
- Total number of observations = n = 100
- Since n is an even number Median = n/2 + (n/2 + 1) observation / 2
- = 100 / 2 + (100 / 2 + 1)
- = 50th + 51st / 2 observation
- = 28 + 29 / 2
- = 57 / 2
- = 28.5
Therefore the median will be 28.5
