Description Author  

This class can calculate the Cronbach Alpha internal consistency (reliability) measure.

It takes as parameter an array with sets of values that usually represent the answers given by respondents of a survey in the form of a scale.

This class processes the sets of values and computes the internal consistency using the Cronbach Alpha measure.
