Abstract
Abstract A method for the graphic representation of statistical data derived from quality control of testing carried out by analysis laboratories has a laser printer instructed by a personal computer produces the graphic representation on a sheet of A4 format paper. The graphic representation printed for each of the analysis laboratories in the quality control program has a Youden graph, a statistical table and a Shewhart diagram.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
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.
Claim 2
Independent Claim
150 words
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.
Claim 3
Dependent Claim
38 words
The method of claim 1, wherein the inputting the statistical data step includes inputting statistical data which includes lower and upper limits, coefficient of variation, and mean of percentage deviation of the historical data of the analysis laboratories.
Claim 4
Dependent Claim
64 words
The method of claim 1, further comprising the steps of: preparing a legend for the Youden graph defining a symbol which represents the historical data of the designated analysis laboratory using the computer; printing the legend on the hard copy medium using the printer; and printing the defined symbol representing the historical data of the designated laboratory on the Youden graph using the printer.
Claim 5
Dependent Claim
49 words
The method of claim 3, further comprising the step of printing a designated analysis laboratory table on the hard copy medium using the printer, the table includes a code of the designated analysis laboratory, period of examination, the historical data of the designated analysis laboratory, and the statistical data.
Claim 6
Dependent Claim
49 words
The method of claim 1, further comprising the step of printing a designated analysis laboratory table on the hard copy medium using the printer, the table includes a code of the designated analysis laboratory, period of examination, the historical data of the designated analysis laboratory, and the statistical data.
Claim 7
Dependent Claim
122 words
The method of claim 5, wherein the step of printing the Youden graph includes printing the Youden graph on a left half of the hard copy medium using the printer, the hard copy medium being a sheet of paper having an A4 size format; the step of printing the legend includes printing the legend above the Youden graph using the printer; the step of printing the designated analysis laboratory table includes printing the designated analysis laboratory table in an upper right half portion of the A4 paper using the printer; and the step of printing the Shewhart diagram includes printing the Shewhart diagram in a lower right half portion of the A4 paper below the designated analysis laboratory table using the printer.
Claim 8
Dependent Claim
24 words
The method of claim 1, further comprising printing connecting lines between data points representing the historical data on the Shewhart diagram using the printer.
