Is MaxDiff a conjoint?
MaxDiff is a statistical relative of conjoint analysis. It derives its name from “maximum difference” scaling, also called best-worst scaling. Traditionally, MaxDiff treats each product as an individual item, whilst conjoint treats products as a combination of attribute levels.
What is conjoint analysis Sawtooth?
Description. Conjoint (trade-off) analysis is one of the most widely-used quantitative methods in Marketing Research. It is used to measure preferences for product features, to learn how changes to price affect demand for products or service, and to forecast the likely acceptance of a product if brought to market.
What are MaxDiff utility scores?
A utility score is a measure of relative desirability or worth. When computing utility scores using logit, latent class, or HB every item in the MaxDiff project receives a utility (preference score). The higher the utility, the more likely the item is to be chosen as best (and not chosen as worst).
Is MaxDiff a discrete choice?
You may have seen or used conjoint or maxdiff analysis in the past — both of which can be considered forms of discrete choice models, at least as how they are normally applied to product pricing/packaging problems.
How is MaxDiff calculated?
Definition: MaxDiff analysis is a survey-based research technique used to quantify preferences. A MaxDiff question shows respondents a set of items, asking them to choose what is most and least important. When the results are displayed, each item is scored, indicating the order of preference.

What is anchored MaxDiff?
Anchored MaxDiff lets the researcher draw a line (a utility boundary) between important and unimportant items (positive vs. negative impact, buy or no-buy, etc.). That utility boundary, for example, could be set at 0.
What is the difference between conjoint and discrete choice?
“The difference between discrete choice models and conjoint models is that discrete choice models present experimental replications of the market with the focus on making accurate predictions regarding the market, while conjoint models do not, using product profiles to estimate underlying utilities (or partworths) …
How do I create a MaxDiff survey?
To create a MaxDiff survey, create a survey as normal, and then add a MaxDiff question where you see fit. You can add an unlimited amount of attributes for respondents to evaluate. You can display up to fifty sets (50) or display all attributes inside one set.
What is maximum difference scaling?
Maximum Difference Scaling (MaxDiff) is a survey research technique for obtaining preference scores for a list of items. It allows you to prioritize a set of product features or test concepts. In a MaxDiff exercise, survey participants are asked to select their most and least favorite type of candy.
How does maxdiff work for scaling multiple items?
MaxDiff makes it easy for researchers with only minimal exposure to statistics to conduct sophisticated research for the scaling of multiple items. The resulting item scores are also easy to interpret, as they are placed on a 0 to 100 point common scale and sum to 100. How does MaxDiff work?
Are there any biases in the maxdiff question?
The MaxDiff question is simple to understand, so respondents from children to adults with a variety of educational and cultural backgrounds can provide reliable data. Since respondents make choices rather than expressing strength of preference using some numeric scale, there is no opportunity for scale use bias.
How many items are included in a maxdiff exercise?
MaxDiff exercises focus on estimating preference or importance scores for typically about 15 to 40 items—though hundreds of items could be accommodated in advanced applications. We typically estimate item scores for each individual using a hierarchical Bayes (HB) methodology.
How many maxdiff questions do I need to answer?
Respondents typically complete eight to fifteen such MaxDiff questions. The combinations of items are designed very carefully with the goal that each item is shown an equal number of times and pairs of items are shown an equal number of times.
