A researcher working at the psychology institute investigates alcohol abuse among adolescents. The researcher designed a questionnaire with 12 items using Likert scales ranging from 1 (completely disagree) to 5 (completely agree). An example of an item is: When I go out, I often consume more than 5 alcoholic beverages. The answers of 608 adolescent girls (1) and boys (2) to the 12 items are in the dataset. Note: higher scores on the questionnaire reflect more alcohol abuse.
What is the highest correlation between an item and the corrected item total? (3 decimals)
Open the dataset below to answer this question:
The highest correlation between an item and the corrected item total is 0.824 (ask for scale if item deleted descriptives when conducting the reliability analysis and look for the item-corrected total correlation).
