What is the median raw score of the marks obtained by the seven students in Chemistry?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 84.5.
Arranging the scores of chemistry in increasing order = 35, 50, 60, 65, 65, 75, 80
There are 7 units.
Therefore median = = 4th = 65
Total marks in chemistry = 130
Median raw score of the marks obtained by the seven students in Chemistry = = 84.5
