Question 0

Cronbach’s Alpha

Answer 0

• internal reliability: assesses internal consistency of test items
• examines inter-correlations b/w test items
• if items reliably assessing the same construct them they should inter correlate
• higher Cronbach’s alpha = higher inter correlation among test items
• reporting Cronbach’s alpha
