In this Geogebra worksheet, you will be working with two sets of data, individual player points per game for the Philadelphia 76ers and the Golden State Warriors. The 76ers data is in the left column, and the Warriors are in the right column. The Warriors are ranked first in team points per game, and Philadelphia is ranked 30th, accoridng to nba.com/stats.
The first thing you’ll have to do is find the mean of the individual data sets. First, highlight all the data in the first column, then click on the last button on the toolbar, and then click mean. This is the average of the data set. Repeat this for the second set of data as well. Record the answers here.
The next activity you’ll do is make some different plots and graphs. Highlight the first column, and then click on the second button of the toolbar. Then change the graph type to Box Plot. Here you can see a visual of the five-statistic summary, which includes min, max, quartile 1, median, and quartile 3. Once you have a box-plot, then click on the first button on that page. It will look like a weird E with an x. You can now view a variety of statistics. Record the last 5 statistics. Also record your thoughts on the box plot. Does it look symmetric, or does it look heavy on one side? Repeat this process with the second column of data.
When doing the second column of data, do you notice anything different about the box plot than the first box plot? What is it? Those two data points not in the box plot are called outliers. Why do you think they are there?
After you complete this, compare the two sets of data. Do you think individual player points per game influences the total number of points a team scores? Or do you think there are other factors as well. Write a summary of your findings and beliefs.
