Document Summary

If an internal item analysis shows inconsistent relationships between items included in an index and the index itself something is wrong with the index. If the index fails to predict strongly the external validation items conclusion is ambiguous. Choose between 2 possibilities: index does not adequately measure the variable in question, validation items do not adequately measure the variable and thereby do not provide a sufficient text of the index. Not all indicators of a variable are really important or equally strong. Each item going into a composter measure may have a different intensity in terms of the variable. Scales offer more assurance of ordinality by tapping the intensity structures among the indicators. 4 scaling procedures: bogardus social distance scale. Measures the wiliness of ppl to participate in social relations of varying degrees of closeness with other kinds of people. Clear differences of intensity suggest a structure among the items.
