Data Set A- 7,7,7,9,9,9,10
Data Set B- 4,6,6,6,8,9,9,9,10,10,10
Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set
data
Eliminate any outliers from the samples. Redo part 1 for each
variable (if necessary, if not...

The following data represents the winning percentage (the number
of wins out of 162 games in a season) as well as the teams Earned
Run Average, or ERA.
The ERA is a pitching statistic. The lower the ERA, the less runs
an opponent will score per game. Smaller ERA's reflect (i) a good
pitching staff and (ii) a good team defense. You are to investigate
the relationship between a team's winning percentage - ?Y, and its
Earned Run Average (ERA)...
