Statistics and Figures

Since traditional psychometric methods for reliability can not be used to calculate specific parts in a test, we use so called "New Quality Analysis" (simlilar to the methods used by Dr. Ivan Ivec) to be able to determine the quality of the intervals listed below. A New Quality figure is often about 10-15% lower than the corresponding Cronbach's Alpha and it generally correlates with tradtional reliability quite well.

We are licensing Calut Jean Mathieu's tool to calculate this this data (the only tool that can do this). Please contact about inquiries for using this tool.
