Question: Suppose that I performed a reliability analysis to determine whether high school students' grades in four different subjects (English. Math, Science. Social Studies) formed a reliable scale with a high Cronbach's alpha. I performed the analysis and got the results presented in the two tables below.
- What is the reliability of this scale, as indicated by the Cronbach's alpha? (1 pt) Is this a high or low level of reliability?
- Which item seems to be contributing the least to the overall Cronbach's alpha? (4 pts)
- Which item. if any, would you recommend removing from this scale? (3 pts)
