Step-by-step explanation:
Given the data:
12, 15, 7, 14, 12, 3, 16, 15, 19, 20, 12, 9, 18, 21
Reordering the data:
3, 7, 9, 12, 12, 12, 14, 15, 15, 16, 18, 19, 20, 21
Mean = Σx / n = 193 / 14 = 13.76
The Median :
1/2(n+1)th term
15/2 = 7.5th term
(14 + 15) / 2 = 14.5
First quartile (Q1) :
1/4(n+1)th term
15/4 = 3.75th term
= 12
Q3 :
3/4(15)th term = 11.25 th term
Q3 = 18
Interquartile range = Q3 - Q1
Interquartile range = 18 - 12 = 6
