Quizplus · Accepted Answer

Thurstone's method of equal intervals, Guttman's cumulative method, and Likert's summative method are the three main approaches to measuring attitudes. Thurstone's method of equal intervals involves asking a panel of judges to rate a set of statements or questions on a scale of agreement or disagreement, and then calculating an average score for each statement or question. Guttman's cumulative method involves creating a set of statements or questions that increase in intensity or extremity and then asking respondents to answer either yes or no to each item. Likert's summative method involves creating a scale of several statements or questions and asking respondents to indicate their level of agreement or disagreement with each one. These three methods are widely used and have been shown to be reliable and valid measures of attitudes.
