Surveys

Get Van Westendorp aggregate results

Returns the aggregated Van Westendorp Price Sensitivity Meter analysis for a van_westendorp question: the four cumulative respondent-price curves (Too cheap / Bargain / Expensive / Too expensive), the four named price intersections (PMC, OPP, IPP, PME), per-bucket histograms, and a confidence signal. Useful when the caller wants the analyzed price points without parsing every respondent's raw quartet themselves.

nmsnumber[]

Percentage of respondents for whom each price is within their acceptable range — neither too cheap nor too expensive — computed as max(0, 100 − tooCheap − tooExpensive) at each price step (indices align with the curves). Not the full Newton-Miller-Smith purchase-probability model, which requires extra trial questions this question type does not collect.
