| Abstract: | Gathering information or collecting data is the norm in school systems across the nation. Using that data to make informed decisions should necessitate the use of statistical tools. One such tool, developed by Walter A. Shewhart at Bell Laboratories in 1924, was the ‘Control Chart,’ a means of determining whether a process had been operating in a state of statistical control or operating in the presence of special causes of variation warranting corrective action. Use of control charts has long been an industry practice. As a school district interested in continuous quality improvement, Beloit Turner explored the application of control charts to a number of instructional and non-instructional areas early on in a restructuring project. This article looks at five such explorations. |
