Answer to Question 1

A constant-sum scale demands that respondents divide points among several attributes to indicate their relative importance. It requires respondents to understand that their response should total to the number of points being allocated. This technique may be used for measuring brand preference and is similar in approach to the paired-comparison method.

Although the constant-sum scale is widely used, strictly speaking, the scale is flawed because the last response is completely determined by the way the respondent has scored the other choices.

Answer to Question 2
