Question

The weight of 10 students in kg are 36 45 31 52 35 40 55 60 38 44 find the median weight

Answer 1

Answer:

Step-by-step explanation:

Arrange the data in ascending order

31, 35, 36, 38,40, 44, 45, 52, 55, 60

Here no of observations n = 10 which is even

In such a case median us defined as the mean of the n/2 and ( n/2 + 1)st observations

n/2 =10/2 = 5

n/2 + 1 =5+1 = 6

So median is the mean of 5th and 6th observation

= (40+44)/2

=84/2

=42 kg

So median weight is 42 kg
