Answers
Answer:
Median = 28+29/2= 57/2= 28.5
Given : Sample of ages (in months) of 18 children at a day care:
36, 42, 18, 32, 22, 22, 25, 29, 30, 31, 19, 24, 35, 29, 26, 36, 24, 28.
To Find : The median age of the children is...
Solution:
36, 42, 18, 32, 22, 22, 25, 29, 30, 31, 19, 24, 35, 29, 26, 36, 24, 28.
arrange the data in the order
18, 19, 22, 22, 24, 24, 25, 26, 28, 29, 29, 30, 31, 32, 35, 36, 36, 42
Data points are 18
Hence Median will be Mean of ( 18/2 th and 18/2 + 1 th ) term
= Mean of 9th and 10th term
9th term = 28
10th term = 29
Median = (28 + 29)/2 = 28.5
The median age of the children is 28.5
