Max Diff Scaling

MaxDiff is a methodology developed by Jordan Louviere et al., that results in interval scale measurements that are based on comparative judgments that can be easily performed, even when the number of attributes is not small. The task presents respondents with a set of items, usually 3 to 6, and simply asks them to select the most preferred and the least preferred in the set (or the most important, least important; best item, worst item, etc. In fact the method is also referred to as Best/Worst scaling). Respondents can typically handle a number of these evaluations, and may be asked to respond to 15, 20, or more sets.

"This is an excellent resource that guided me while going through with my research online. It isn't specific only to SurveyAnalytics tool but also is about the general principles one needs to stick to increase the response rates and minor tweaks in language to make the existing questionnaire more effective. I recommend that not only dummies but even people with some experience in online surveys read this book once.."
