While for reliability items the value is 0.82 and 0.84 produces a good value. while the Cronbach alpha index also produces a Cronbach Alpha value yields a value of 0.93 (produces a very good value). Determination of sample size uses the Item Measure table based on the accuracy of confidence measurements (95%).
