   For his thesis research, a graduate student measured the degree of self-confidence of students measured with a scale consisting of 6 items and ranging from 1 (low self-confidence) to 10 (high self-confidence). The Cronbach’s alpha of this scale is 0.78.

   The Cronbach’s alpha could be increased by…

   
   
   1. FALSE: Including additional respondents in the study (increasing N).
   2. FALSE: Using a z-score of 1.96 as the critical limit, instead of 2.
   3. FALSE: To remove an item with a high positive “Corrected item-total correlation.” remove.
   4. TRUE: To remove an item with a value of 0.82 at “Cronbach’s alpha if item deleted.” delete.
