MaxDiff, Conjoint, Driver Analysis
Which method carries which decision, how much sample it needs, and where studies go wrong
What you get
- A decision table: which question needs which method and which number it delivers
- Rules of thumb for items, sets, tasks and sample size per method, given as practical ranges
- Why correlations and regression coefficients mislead in satisfaction data and what LMG changes
- Van Westendorp with all four price points, including the indifference price most reports skip
- Reporting patterns: which chart belongs on the one slide and what goes in the appendix
- A twelve-question checklist for the next study design
In short
Four methods answer four different questions, and most failed studies asked the wrong one. MaxDiff ranks a list, choice-based conjoint values combinations and prices, driver analysis explains a score, Van Westendorp and Gabor-Granger measure price thresholds. This guide covers design, estimation, sample size and the classic mistake for each method, puts them side by side in one table and ends with a checklist for your next study design. Sample-size rules of thumb are labelled as such; they come from practice, not from a textbook.
