The Likert scale is developed using the summated ratings method, where respondents rate their level of agreement with a series of statements using a standardized scale (often ranging from strongly agree to strongly disagree). The total score is calculated by summing the ratings across all statements, resulting in a quantitative measure of the respondent's attitude or belief. The Thurstone scale is also a type of attitude measure but uses a different method for generating scores. The Rorschach Test and Thematic Apperception Test are both projective personality tests and do not use the summated ratings method.
