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.

Cronback Alpha is a measure that can be used to determine the level of consistency of sets of values, like for instance the responses that a group of users give to a survey.
This class provides a PHP implementation of the calculations necessary to compute the Cronbach Alpha factor.
