The data in the accompanying spreadsheet is statapult group data from a previous year. Each member in a group of five launched balls from the statapult twelve times yielding a total of 60 observations. Answer the following questions: 1) Describe the center, spread, and shape the data overall (all 60 data points, making no distinction between workers). Do so using whatever numeric and graphic measures you see fit. 2) Do the same thing for the 12 data points by each worker. 3) Is there a difference in the data depending on who launches the ball?
