This is a guide for everything you need to know about MaxDiff. It covers the “what is?” and the “how to…” of different approaches to the analysis, from preference share to profiling latent classes and finally how to interpret the analysis. There are worked examples, shown in Displayr and R.
Introduction
What is Max Diff? Have you ever needed to know what your customers prefer? MaxDiff (otherwise known as Best-Worst Scaling) quite simply involves respondents indicating the ‘Best’ and the ‘Worst’ options out of a given set so that we can gain an understanding of consumers’ preference choices. This can be from how they feel about specific brands or products and to know which features make a difference and are of value to the consumer.
A Beginners Guide to MaxDiff MaxDiff is a research technique for measuring relative preferences.
How MaxDiff Analysis Works This post explains the basic mechanics of how preferences can be measured using the data collected in a MaxDiff experiment.
