How this service works
Training assessments — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation 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 category frequency table showing counts and proportions for each unique course_group value, and (2) a two-measure correlation report (e.g. Pearson and Spearman) between the pre_score and post_score columns across all supplied rows. No external lookups or predictions are made; all analysis uses local engines on the submitted data.
Example use cases
Post-training effectiveness analysis
“Here are 150 training assessment records with course_group, pre_score, and post_score — can you compute the frequency of each course group and tell me whether the pre-test scores are correlated with the post-test scores?”
Learning program cohort breakdown
“I've got assessment data for four training cohorts labeled group-a through group-d, each with pre and post scores. Can you give me the count of each cohort and check if pre_score and post_score are statistically correlated?”
HR training audit correlation report
“Our HR team has 80 rows of employee training records, each with a course_group, a pre_score, and a post_score. Can you produce a category frequency report for the groups and a two-measure correlation between the pre and post scores?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-11-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular training assessment data with a course/group category column and paired numeric pre/post scores, and you need both a group frequency breakdown and a correlation statistic in a single low-cost call. It is ideal for education analytics, HR training evaluation, or learning management reporting where you want two complementary statistical views (distribution + relationship) without setting up a full analytics pipeline. It handles up to 200 rows per call for $0.01 USDC.
Side effects
- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — exceeds limit
- Missing required fields (row_id, course_group, date, pre_score, post_score) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- All pre_score or post_score values are null — correlation cannot be computed
- Payment of 0.01 USDC not completed via x402 — request blocked
