During the medical check-up of 35 students of a class, their weights were recorded as follows :
Weight (in kg) Number of students
Less than 38 0
Less than 40 3
Less than 42 5
Less than 44 9
Less than 46 14
Less than 48 28
Less than 50 32
Less than 52 35
Draw a less than type ogive for the given data. Hence obtain the median weight from the graph and verify the result by using the formula.

Answer:
46.5 kg is median
Step-by-step explanation:
Weight (in kg) Number of students Frequency More than CF
Less than 38 0 0 35
Less than 40 3 3 32
Less than 42 5 2 30
Less than 44 9 4 26
Less than 46 14 5 21
Less than 48 28 14 7
Less than 50 32 4 3
Less than 52 35 3 0
46.5 kg is median
Estimated median = 46 + ((35/2) - 14) * 2 /14
= 46 + 0.5
= 46.5 kg
