From the above, randomly select 20 players from each team. Why is it important to randomly select these players?

Next, open the spreadsheet. Enter the weight of the 20 randomly selected players for the Braves, Cubs, and Red Sox into Group 1, 2, and 3, respectively.

Questions

How do their weights compare?

Do there appear to be any outliers?

What is the IQR for Group 1, 2 and 3?

What do the measures tell us about the Braves, Cubs and Red Sox?

Graph box-plots for each of the teams using the same scale for weights.
