Find a research approachMaxDiff study planner
How much should each person evaluate?
Compare item exposure, question counts, reporting groups, and survey time. Download a MaxDiff plan with its assumptions explained.
Plan a MaxDiff studyConjoint questionnaire planner
What can we reasonably ask in a conjoint survey?
Compare choice questions, product layouts, and survey time. Build a questionnaire plan with clear assumptions and research references.
Use the plannerSurvey length and respondent-burden estimator
How much are you asking of respondents?
Estimate questionnaire duration by format, route, and device. Review open ends, grids, media, lookup effort, and embedded choice exercises.
Use the estimatorSurvey sample-size calculator
How precise could our survey results be?
Plan usable survey sample sizes, compare margin of error by reporting group, and calculate Wilson confidence intervals with explicit sampling assumptions.
Plan survey precisionDetectable-difference calculator
Could we detect a meaningful difference?
Calculate required sample, detectable differences, or statistical power for independent percentages and means. Compare assumptions and download your plan.
Plan a group comparisonB2B recruitment planner
Can your recruitment plan reach the people you need?
Estimate screening effort, compare unique supply with audience quotas, and explore how qualification and quality assumptions affect usable yield.
Use the estimatorBrand tracker study planner
Which tracking schedule can support our decisions?
Compare collection and reporting cadence, sample sizes, priority audience bases, detectable changes, and annual costs from your own assumptions.
Plan a brand trackerConcept and message test planner
What should each person evaluate, and what can the study establish?
Compare test designs, plan exposure and audience allocation, calculate supported independent comparisons, and export your study specification.
Plan a concept or message testKano feature-classification analyzer
What do people expect from this feature?
Analyze paired Kano survey responses locally. See all six categories, Better/Worse indices, audience differences, and bootstrap classification stability.
Analyze feature responsesNPS confidence and change calculator
How uncertain is our NPS, and what changed?
Calculate Net Promoter Score, response composition, confidence intervals, and change between independent samples. Compare change with your business threshold.
Analyze NPS confidence and changePrice-change and volume break-even calculator
How much can volume change while preserving current profit?
Compare the volume loss a price increase can absorb or the sales gain a discount needs. Include cost changes, revenue thresholds, and your own volume scenarios.
Calculate a price changeVan Westendorp price-perception analyzer
What prices feel reasonable to your audience?
Import respondent prices, review inconsistent answers, compare conventional price ranges, and measure resampling stability. Data stay in your browser.
Analyze price perceptionsWeighting and effective-sample-size diagnostic
How concentrated are our survey weights?
Inspect survey weights, Kish effective sample size, weighting efficiency, concentration, and reporting groups. Read data locally and download a methods report.
Check survey weightsQualitative interview and focus-group planner
Whom do you need to hear from?
Choose a format, plan audience coverage and attendance, estimate session effort, and set a review point before adding more fieldwork.
Use the plannerGabor–Granger pricing analyzer
Which tested prices have the highest stated revenue and contribution?
Analyze stated purchase response at tested prices. Compare revenue and contribution, import local CSV records, inspect uncertainty, and export the methods.
