Out of Control!

Published on 06/09/2008

Activity Overview

Students make XY Line Plots and scatter plots to create run charts and control charts (types of time plots) to determine if a manufacturing process is statistically stable. Students begin by looking for any unusual patterns or trends in variation and then calculate sample means and upper and lower control limits to create control charts which they then interpret.
