Interpret the reliability coefficient: I looked at the value of Cronbach's alpha for the instrument, which was -1.669. Since Cronbach's alpha measures the internal consistency of a scale, a negative value indicates that the average covariance among items is negative, violating the assumptions of the reliability model. Step 2.
