Section 14-1 Review and Preview

Review In Section 2-1 we noted that an important characteristic of data is a changing pattern over time. Some populations change over time so that values of parameters change.

Preview The main objective of this chapter is to learn how to construct and interpret control charts that can be used to monitor changing characteristics of data over time. That knowledge will better prepare us for work with businesses trying to improve the quality of their goods and services.

Preview Control charts are good examples of visual tools that allow us to see and understand some property of data that would be difficult or impossible to understand without graphs.
