This presentation outlines: -MaxDiff Scaling -The Difference Between MaxDiff and Rating Scales -How to Setup MaxDiff in Survey Analytics -Analyzing the Results MaxDiff scaling (AKA Best/Worst Scaling) in surveys allows you to conclude what the most and least preferred items are. MaxDiff scaling is easier for respondents to answer and is highly preferred over basic rating scales when needing to collect a lot of preference data. Alongside from being user friendly and visually appealing in your survey, you can ask 15-20 sequences of MaxDiff questions and they are simple for the respondent to answer. MaxDiff preference data is measured on a scale of 100% or a 100 point scale making your data more quantifiable and easier to analyze.

1. MAXDIFF SCALING
Get More Quantifiable Data and Less Respondent Fatigue

2. MAXDIFF SCALING
MaxDiff Scaling is based on
comparative judgments that can be
easily performed, even when the
number of attributes is not small
(up to 30).
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.

4. MAXDIFF SCALING (CONTINUED)
MaxDiff Scaling is Also Known as
Best/Worst Scaling
Respondents can typically handle a
number of these evaluations, and
may be asked to respond to a series
of MaxDiff questions to gather more
preference data.

5. *Cool New Stuff*
MAXDIFF VS. RATING SCALES
MaxDiff has less much less respondent
fatigue compared to rating scale
questions.
Survey fatigue is so low that you can
run even up to 15-20 different MaxDiff
questions if needed.
Why? because you are only asking for
Most/Least or Love/Hate combos.

7. *Cool New Stuff*
MAXDIFF VS. RATING SCALES (CONTINUED)
The MaxDiff Share of Preference Data
is up to100%, or a 100 point count.
If there is a 68% preference to
Hawaiian vacation vs. 48% Vegas
vacations then you can conclude there
is a 20% difference in preference
between the two vacations.

8. *Cool New Stuff*
MAXDIFF VS. RATING SCALES (CONTINUED)
In rating scales, it’s hard to measure what
a 4/5 vs. 2/5 scale really means. Sure you
can say a 2 point difference, but what does
that 2 point equate to?
Rating scales are more difficult to quantify
than MaxDiff data output

SETTING MAXDIFF ATTRIBUTES
Attribute Settings:
Maximum Attributes: Define
how many attributes out of
the list you created that will
be tested for each
respondent.
Example:
All = All attributes tested
6/9 = Respondent will only
see 6 out of list of 9
