In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. Five test vehicles of each type were crashed, with the results shown below. Research question: Are the mean crash damages the same for these three vehicles?
Crash Damage ($)
Goliath Varmint Weasel
1,600 1,290 1,090
760 1,400 2,100
880 1,390 1,830

To find the mean, add all items and divide by the number of scores you have.
Goliath mean = 1322
Varmint mean = 1376
Weasel mean = 1638
We can see that these means are not the same.
