    Question

    Suppose we get the following results from a reliability analysis of a scale with 7 statements. What can we best to do with item5? And why?


    1. FALSE: This item is best left unchanged in the scale retained, because the value at “Cronbach’s Alpha if Item Deleted” is higher than 0,80.
    2. FALSE: This item is best removed from the scale because the Item-Total Correlation has a high negative value.
    3. TRUE: This item is best ompolled (recoded), because the Item-Total Correlation has a high negative value.
    4. FALSE: We can best standardize this item, because the z-score of item5 will thus have a high positive Item-Total Correlation.
    5. FALSE: It is best to remove this item from the scale, because the value at “Cronbach’s Alpha if Item Deleted” is higher than 0.80.

    Solution

    all three are correct: diferent sample sizes, significant levels, samples


    1. False
    2. False
    3. True
    4. False
    5. False
