The guide is divided into fivesections. The first section contains the following preliminaryinformation: individual assessment sheet, instructor notes, andprimary objectives. The second section is a course outline, and thethird section contains the module lessons and worksheets, which aredevoted to the following topics: using a calculator, calculatingtotals, calculating averages, calculating process averages, roundingoff decimals, and calculating ranges. The final two sections consistof answers to the worksheets and pretests and posttests. ---AA*1'.AA-****Reproductions supplied by EDRS are the best that can be madefrom the original ******************************

The charts are used to record, calculate, plot data, andconnect plotted points to find a pattern. SPC charts allow associates to recognize whether aprocess is going to produce defects or errors. Therefore, associates may take corrective action to avoid production problems.19Workforce Education Services 5/1996Paee 5BEST COPY AVAILABLE
