Introducing…
Sawtooth Software’s MaxDiff Analyzer
(A Web-Based Analysis Tool for Maximum Difference Scaling Studies)
![Page 2: Introducing… Sawtooth Software’s MaxDiff Analyzer (A Web-Based Analysis Tool for Maximum Difference Scaling Studies)](https://reader033.vdocuments.us/reader033/viewer/2022061602/56649f145503460f94c28569/html5/thumbnails/2.jpg)
What MaxDiff Analyzer Offers…• TURF (Total Unduplicated Reach and Frequency)
optimization searches
– For optimizing bundles of items to best “reach” respondents
– Employs “exhaustive search”
– Advanced functions such as:• Prohibit certain items from occurring within the same set• Force certain items into sets

What MaxDiff Analyzer Offers…
• Automatic rescaling of scores if using CBC/HB
– If you use CBC/HB to compute your MaxDiff scores, you know that there is some extra effort to insert the “omitted” item and to set all the scores on a probability scale
– MaxDiff Analyzer does this for you

What MaxDiff Analyzer Offers…
• Confidence intervals on scores
– For either the “probability-scaled” or “raw” scores, MaxDiff Analyzer will report the 95% confidence interval
• Analysis by Segments, including Weighting

You can download the summary table or the rescaled individual scores
![Page 11: Introducing… Sawtooth Software’s MaxDiff Analyzer (A Web-Based Analysis Tool for Maximum Difference Scaling Studies)](https://reader033.vdocuments.us/reader033/viewer/2022061602/56649f145503460f94c28569/html5/thumbnails/11.jpg)
You can segment the scores as well, such as by categories of age…
(Weighting may also be applied, but it is not in this example.)

The Basic Simulator…
Check which items to include in the simulation…

Simulator Output…
Read: if only these three items were offered to respondents, what % of respondents would prefer each item?
Item 8 is preferred by 47.6% of the sample, etc.
(“First Choice” and “Share of Preference” simulation options available.)

TURF Analysis: Finding an Optimal Bundle of Items
Let’s search for the three items (out of our 20) that taken together as a bundle (portfolio) would include items that were attractive to the most amount of people in terms of encouraging them to reenlist in the Navy.

About 1 second later (n=250)…
Read: the most effective bundle of items is {1, 5, 20}
