    Question

    For a project, two interns are researching the re-experiences of children who have experienced a car accident. Below is the output of the reliability analysis.

    Which item(s) would you like to remove in the next step of this analysis? And why?


    1. FALSE: Item 10 because the dispersion (variance) becomes smallest if you remove this item.
    2. FALSE: Items 6 and 7 because the item-rest correlations are too small.
    3. FALSE: Items 6 and 7 because Cronbach’s alpha increases when you remove these items.
    4. TRUE: Item 6 because Cronbach’s alpha increases if you remove this item and because this item-rest correlation is smallest.
