What You Can Do

Claude helps you design statistically sound market research studies from hypothesis formation through analysis. You'll calculate sample sizes, statistical power, and interpret confidence intervals and hypothesis tests with professional rigor. Transform raw survey and experiment data into actionable business insights backed by solid statistics.

Features

Study Design & Methodology

Develop rigorous research frameworks aligned with your business questions, including hypothesis specification, study design type (survey, experiment, observational), and measurement protocols.

Statistical Power Analysis

Calculate required sample sizes to achieve your target statistical power, accounting for effect size, significance level, and study design complexity.

Hypothesis Testing Framework

Select and interpret appropriate statistical tests (t-tests, chi-square, ANOVA, regression) based on your data type and research question.

Confidence Interval Calculation

Quantify uncertainty in your results with confidence intervals, showing the range of plausible true values for your key metrics.

Sample Size Justification

Determine adequate sample sizes before data collection, balancing statistical rigor with practical constraints like budget and timeline.

Statistical Assumption Validation

Check normality, homogeneity of variance, and other assumptions required for different statistical tests, with alternative methods when assumptions are violated.

Results Interpretation & Reporting

Translate p-values, effect sizes, and confidence intervals into clear business insights distinguishing statistical significance from practical significance.

A/B Test Analysis

Analyze experiment results with appropriate statistical tests, accounting for multiple comparisons and sequential testing when applicable.

Example Output

Customer Satisfaction Survey Design

Sample Size Recommendation: 385 respondents (95% confidence, 5% margin of error, 50% expected satisfaction) Power Analysis: 80% power to detect 10-point difference on 100-point scale Recommended Test: Two-sample t-test for comparison groups

A/B Test Analysis Results

Control Conversion: 12.0% (n=2,000) Treatment Conversion: 15.0% (n=2,000) 95% Confidence Interval: [1.2%, 5.8% improvement] P-value: 0.0032 (statistically significant) Effect Size (Cohen's h): 0.069 (small but meaningful lift) Interpretation: Strong evidence of improvement; recommend rollout with monitoring
