4. Deciding Which Items to Select l Throw out items that have a low correlation with the total (summed) score across all items. l For each item, get the average rating for the top quarter of judges and the bottom quarter. l Do t-test; higher t-values mean the items are better discriminators, so keep them. Item-total correlations Internal consistency

5. How Does Respondent Use? l Gives a 1-to-5 (or sometimes a 0-to-4) rating for each item on the scale. l Sum these across all items. l This is why this is sometimes called a “summated” scale. l don’t forget to reverse any reversal items.
