Answer:
In this example, it is clear that none of the students have got less than 20% of the marks and only 7 students i.e., only 10% have got greater than 70%.
The mid-range of 65 students comes at 32.5 i.e., 33 students and basis the data, it is clear that the median marks of the class are largely in the range 40% to 50% with a maximum of 40 students falling under this category.
