   Question

   For his thesis research, a graduate student measured the degree of self-confidence of students with a scale consisting of 6 items ranging from 1 (low self-confidence) to 10 (high self-confidence). The Cronbach’s alpha of this scale is 0.74.

   The Cronbach’s alpha could be increased by:

   I.             Adding another item to the scale.
   II.            Removing an item with a low corrected item-total correlation.
   III.           Remove from the scale an item with a value of 0.79 in “Cronbach’s alpha if item deleted”.

   
   
   1. TRUE: I, II and III are true.
   2. FALSE: I is true
   3. FALSE: III is true.
   4. FALSE: II is true
   
   
   1. True
   2. False
   3. False
   4. False
