Msa Spss. The desire is to be able to compare grr to the total variation to determine the of the total variation that is due to the measurement system i e the combined repeatability and reproducibility. In addition msa determines the amount of error derived from the measurement process itself.
The kmo statistic is a summary of how small the partial correlations are relative to the original zero order correlations. Run factor analysis analyze dimension reduction factor and check the box for kmo and bartlett s test of sphericity if you want the msa measure of sampling adequacy for individual variables check the anti image box. Msa analyzes the collection of equipment operations procedures software and personnel that affects the assignment of a number to a measurement characteristic.
The measures of sampling adequacy msa for individual variables are printed as the diagonal elements of the anti image correlation matrix in the anti image matrices table of the factor output.
In addition msa determines the amount of error derived from the measurement process itself. The msa methodologies give you insights into other things but the value of grr is the measure that is focused on by most people. Msa analyzes the collection of equipment operations procedures software and personnel that affects the assignment of a number to a measurement characteristic. In addition msa determines the amount of error derived from the measurement process itself.
