ANOVA Method Results

Select the Constant you would like to use for your study (6 or 5.15):

6 (AIAG Standard): Introduced in AIAG 3rd Edition, this constant assumes that 99.73% of data falls within the Standard Deviation of the mean.

5.15 (Alternate multiplier): Introduced in AIAG 1st Edition, this old AIAG standard assumes that 99% of data falls within the Standard Deviation of the mean.

QI Macros calculations have been tested and validated against the AIAG MSA 4th edition. For more details view this Gage R&R validation test using Ford Motor Co data.

Honest Gage R&R

Added to the Gage R&R MSA 4th and Gage R&R 30-Parts templates in our April 2022 release, this output references Dr. Donald J. Wheeler's belief that there are specific problems with Gage R&R studies:

An Honest Gage R&R Study is a simplified version of a Basic EMP Study (Evaluating the Measurement Process), and Dr. Wheeler believes it provides more in-depth outputs then standard MSA 4th studies - this is found in his book, "EMP III Using Imperfect Data" (pgs. 232-235).

To learn more about why you might consider conducting an Honest Gage R&R, along with definitions regarding these different outputs, click here to read Dr. Wheeler's article.
