Olympic Long Jumps
The chart displayed shows a list of both years and distances for Olympic Long Jumps from 1896
until 2004. During these years, the distances have mostly increased. Using some historical data, it is
evident that the two W

By looking at the group data, it is evident that the fish did not launch as far as the bears
did. We can see this by the mean and the standard deviation. When comparing our group data we

Coins
I used a glass yesterday and 10 pennies to create data for this task. I shook the glass and
dumped the coins out and counted how many landed with heads facing upward. I did this thirty
times so that I co
CHAPTER 12: ANALYSIS OF VARIANCE
12.1 OVERVIEW
Analysis of variance (ANOVA) is a method for testing the hypothesis that three or more population means are equal.
For example:
H0: 1 = 2 = 3 = . . . k
H1: At least one mean is different
