Answer:
Step-by-step explanation:
Given data is 90,30,20,40.
Rearranging the data into ascending order
= 20,30,40,90
As the given number of values is even , we have two middle values, they are
(n/2)th observation and ( n /2 + 1 )th observation.
They are 30 and 40.
∴ Median of the data = 30 + 40 / 2 = 70 / 2 = 35 is the answer.
