1. A method for graphically representing statistical data derived from quality control of testing carried out by analysis laboratories, each analysis laboratory having historical data of the testing, the method comprising the steps of:
- inputting the historical data of the analysis laboratories using a computer;
inputting the statistical data which includes at least a mean and a standard deviation of the historical data using the computer;
preparing a Youden graph based on the statistical data using the computer;
positioning the historical data of the analysis laboratories on the Youden graph using the computer;
printing the Youden graph on a hard copy medium using a printer;
preparing a Shewhart diagram based on the statistical data using the computer;
positioning the historical data for one of said analysis laboratories in standard deviation units on the Shewhart diagram using the computer; and
printing the Shewhart diagram on the hard copy medium using the printer.
