Reliability analysis (approx. 100 words). Calculate the overall internal consistency reliability for two of the factors you have identified (please indicate which two you will focus on). Provide and briefly comment on the Cronbach's alpha values for those two factors [2 pts] For Factor 1 items, The Cronbach's alpha, the estimate is 0.873 (95% CI: 0.828-0.918). With a threshold of 0.70, the scale clearly meets the criterion and shows good internal consistency. All the three items are below the full scale alpha, 0.873 that is hit or push others 0.846, physical fights with other children 0.842 and physical force to defend self 0.772. As the numbers are lower than Cronbach's alpha, leaving any item out overall reliability score will drop. For Factor 2 items, The Cronbach's alpha () = 0.893, which is higher than the threshold 0.70 indicating good internal consistency. harsh words or insults 0.816 verbally aggressive 0.814 verbally lashes out 0.902 Dropping "verbally lashes out" would raise slightly (0.902 > 0.893), suggesting it contributes a bit less coherently than the other items. However, the increase is small and the current is already high; keep all items is this answr correct
