Hi. I have been dealing with Measurement Systems Analysis for almost over a year now. There is a question bugging me for sometime now. It is the sample size we use for analysis. In most sources it says to take mostly 10 parts, however, what would be the reason behind this? Also, is there a way to calculate the required sample size for more accurate measurement systems analysis results? If any of you direct me to a source where I could find examples and explanation it would be greatly appreciated. Thanks
