How Do You Calculate Cronbach Alpha For A Questionnaire? To compute Cronbach’s alpha for all four items – q1, q2, q3, q4 – use the reliability command: RELIABILITY /VARIABLES=q1 q2 q3 q4 . The alpha coefficient for the four items is . 839, suggesting that the items have relatively high internal consistency. How do you
What Is An Acceptable Level Of Reliability? A general accepted rule is that α of 0.6-0.7 indicates an acceptable level of reliability, and 0.8 or greater a very good level. However, values higher than 0.95 are not necessarily good, since they might be an indication of redundance (Hulin, Netemeyer, and Cudeck, 2001). What Cronbach alpha
What Is Reliability And Validity Of Measurement? Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. What is reliability in measurement? The reliability of
