The document discusses several types of attitude scales used to measure opinions and attitudes, including Likert scales, Thurstone scales, Guttman scales, and semantic differential scales. Likert scales use numbered responses to statements to assess level of agreement. Thurstone scales use judges to rate statements and select a set with the least inconsistencies. Guttman scales sum the values of statements a respondent agrees with. Semantic differential scales use bipolar adjective pairs to rate concepts on dimensions of evaluation, potency, and activity.
