How this service works
Training assessments — Two-measure correlation + Explicit missing-value fill: Two-measure correlation + Explicit missing-value fill for supplied training assessments records (pre_score, post_score). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.
Output
Returns two analytical reports: (1) a two-measure correlation report showing the statistical relationship (correlation coefficient) between pre_score and post_score across all supplied rows, and (2) an explicit missing-value fill report showing the chosen field with nulls replaced by the selected method (zero, mean, or median) applied to the non-null values. No external lookups or predictions are made.
Example use cases
Corporate training cohort analysis
“I've got 120 rows of employee training data with pre_score and post_score for two course groups. Can you compute the correlation between their pre and post scores and fill any missing post_scores using the mean?”
E-learning missing score imputation
“My online course dataset has null pre_score entries for some students. Can you fill in those missing pre_scores using the median imputation method and also show me the correlation between pre and post scores across all 80 rows?”
Academic assessment quality check
“I'm running a pilot for a new assessment program with 60 records spread across two groups dated between 2025-01-10 and 2025-03-15. Some pre_scores are missing — fill them with zero and also give me the correlation report between pre and post scores.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-11-184?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have training assessment data with pre_score and post_score columns and need both a correlation analysis and missing-value imputation in a single paid call. It is ideal for education and e-learning datasets of up to 200 rows where you want offline, local statistical computation without any external data lookups, live scoring, or AI-generated predictions. Prefer this over general-purpose analytics tools when you need a cost-effective ($0.01 USDC) bundled report covering both correlation and imputation in one API call.
Side effects
- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, course_group, date, pre_score, or post_score) — validation error
- Date format not matching YYYY-MM-DD pattern — schema validation failure
- Invalid enum value for field or method parameters — rejected with schema error
- All values in the target fill field are null — mean/median imputation may be undefined
- Payment not completed via x402 — request not processed
