Concept explainers
To calculate mean, median, mode, range and IQR.
Answer to Problem 10.2STP
Mode=64
Range=25
IQR=9
Explanation of Solution
Given information:
Formula used:
Range=maximum -minimum
IQR=Q3-Q1 Where Q1lower quartile and Q3is upper quartile
Calculation:
508 n=10
Using mean formula
On solving,
Ordered data: 39, 43, 47, 48, 48, 51, 52, 56, 60, 64
n=10
n is even
Middle terms: 48, 51
On solving,
Mode=64
Minimum=39
Maximum=64
Using range formula
Range=64-39=25
Lower quartile, Q1=47
Upper quartile, Q3=56
Using IQR formula
IQR=56-47=9
