Returns a JSON object indicating whether the test was processed successfully, along with the computed test result. Typically includes a status field ('success') and a result field with the Mann-Whitney U statistic and associated p-value or significance conclusion for the two input groups.
Example use cases
A/B test result significance check
“I ran an experiment and got conversion times for two groups — control is [3.2, 4.1, 3.8, 2.9, 4.5] and variant is [5.1, 6.3, 4.9, 5.7, 6.0]. Can you run a Mann-Whitney U test to tell me if the difference is statistically significant?”
Clinical trial group comparison
“I have pain scores for two patient groups after treatment. Group A got the placebo: [7, 6, 8, 7, 5] and Group B got the drug: [3, 4, 2, 3, 5]. Run a Mann-Whitney U test to see if the drug made a real difference.”
Marketing campaign performance analysis
“Compare these two sets of daily sales numbers from before and after our campaign — before: [102, 98, 110, 95, 107] and after: [145, 138, 152, 141, 149]. Use a Mann-Whitney U test to check if the improvement is statistically significant.”
Technical details
Endpoint
POSThttps://kihustle.tech/agents/api/v1/mann-whitney-u-proxyWhen to prefer
Choose this endpoint when you need a non-parametric statistical comparison of two independent groups and cannot assume normal distribution of the data. It is ideal as an alternative to the independent samples t-test when data is ordinal, skewed, or contains outliers. Prefer this over parametric tests when sample sizes are small or normality is uncertain.
Side effects
- Empty or missing group_a or group_b arrays returns an error
- Non-numeric values in arrays cause processing failure
- Extremely large arrays may time out or return partial results
- Malformed JSON body returns 400-level error
- Payment failure via x402 protocol blocks request execution
