SCHART

This program will produce an S-Chart used in quality control. The user enters in the number of samples (limited to 99 samples) and the sample size for each sample (the sample size must be the same for every sample) and it must be between 2 and 25 (otherwise the program will produce an error message). The program will produce an XYLine of the means of the standard deviations for each sample and it will also graph the Mean Line, the Upper and Lower control limits as well. You must download the lists SCHB3 and SCHB4 as these lists have the weighting factors. Enjoy!
