Solved Examples

Question 1: Find the median of 9, 3, 44, 17, and 15
Solution:

 
Step 1: Arrange the data in ascending order

3, 9, 15, 17, 44

Step 2: N = 5, since n is odd, The number in the middle is taken as the median

 The Median is 15 (The number in the middle) in statistical terms.
 

Question 2: In a group of 33 children, 10 are like ice-cream, 15 are like sweets and 8 are like both ice-cream and sweets. Find the possibility of a child likes either ice-cream or sweet or both.
Solution:

 
P(Ice-cream) = 10, P(Sweets) = 15 and P(Ice-cream and sweets) = 8

We need to calculate P(Ice-cream or sweets) to find the possibility of a child likes either ice-cream or sweet or both.

P(Ice-cream or sweets) = P(Ice-cream) + P(Sweets) - P(Ice-cream and sweets)

= 10 + 15 - 8

= 17
