Answer the following with the help of the data given below:
There are two brands of light bulbs which are brand M and Brand J. Here are the life spans of both brands (in hrs):
Brand M : 100 , 200 , 150 ,120 , 140 , 100
Brand J : 120 , 180 , 190 , 140 , 130 , 110
Which of the brands show less variability?
- Brand J
- Brand M
- Both a and b
- None of the above
The correct answer is: Brand J
Variability=max value - min value
Variability of Brand M= 200-100=100
Variability of Brand J=190-110=80
Brand J shows less variability.
