These diagrams are used frequently in the real world of chemical engineering. In this workshop, your group will examine these three statistical plots and how they can be used to extract information from a set of data. In this case, you will use a set of measurements of cylinder lengths from the set of copper cylinders used in the Workshop #3. These measurements were made with a more accurate and precise caliper set. Directions See the table of cylinder lengths at the end of this document. 1. Create a stem-and-leaf diagram for your data in the space below. See pages 23-26 in the text, if you dont know how to do this. _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ _____ _______________________ Do you recognize one or more data that are potential outliers?
