Most researchers prefer to include at least two questions that measure the same thing (the above survey has three).Īnother example: you give students a math test for number sense and logic. three “agrees” or three “strongly disagrees.” If different answers are given, this is a sign that your questions are poorly worded and are not reliably measuring customer satisfaction.
