Which scale uses checkmark items that respondents assign a numerical value to indicate how favorable or unfavorable a statement is?

• A. Thurstone scale
• B. Likert-type scale
• C. Semantic differential
• D. Projective tests

Answer: (A)

In this approach, a pool of statements about an attitude is prepared, and expert judges rate each statement for how favorable or unfavorable it is toward the attitude object, assigning a numerical weight to every item. These weights create equal-appearing intervals across the items. When administering the scale, the respondent simply marks the statements that describe their own attitude. The overall attitude score is obtained by summing the weights of the endorsed statements. This combination—checkmarking items that have preassigned numeric values reflecting favorability—fits Thurstone scaling best, distinguishing it from Likert-type scales (rating agreement with each item), semantic differential (rating on bipolar adjective scales), or projective tests (interpretive responses).
