مستخلص: | A subset of Statistical Process Control (SPC) methodology known as Control Charting is introduced. SPC methodology is a collection of graphical and inferential statistics techniques used to study the progress of phenomena over time. The types of control charts covered are the null X (mean), R (Range), X (individual observations), MR (moving range), p (measure of successes), and U (number of events per unit). Uses of charts in the binomial case and the Poisson case are considered. These charts provide the researcher with a combined graphical and hypothesis testing procedure for assessing the stability of various types of data collected across time. The details of constructing each of these charts and the methods for hypothesis testing are described. Examples drawn from the field of education illustrate chart construction. SPC procedures described are understandable by researchers who are not mathematically oriented; whereas other procedures often recommended in the statistically-oriented literature on single-subject design are not easily understood by these researchers. All of the SPC techniques introduced can be modified to allow the analysis of data from one-way multiple group designs and factorial designs. Although these charts do not represent all the control charting techniques used in process control, they are the ones most applicable to educational research. Five tables present sample data, and seven graphs illustrate SPC charts. (SLD) |
