How this service works
Tutoring sessions — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation for supplied tutoring sessions records (session_minutes, session_count). 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 how many records fall into each course_group value, and (2) a two-measure correlation report quantifying the statistical relationship between session_minutes and session_count across the supplied rows. No external data is fetched; all computation is performed locally on the submitted dataset of up to 200 rows.
Example use cases
Course Group Attendance Frequency Analysis
“I have 150 tutoring session records across groups like 'Math-101', 'English-202', and 'Science-303' — can you count how often each course_group appears and also tell me whether longer sessions correlate with higher session counts?”
Tutoring Program Engagement Report
“Here are 80 tutoring session rows with course_group, date, session_minutes, and session_count — give me a frequency table by group and show the correlation between session minutes and session count so I can see how engagement patterns differ.”
Detecting Session Length vs Volume Relationship
“I've got a dataset of 60 tutoring sessions across two groups, group-a and group-b, with session_minutes and session_count filled in — run the category frequency report and the two-measure correlation so I can tell if busier days also have longer sessions.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-16-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular tutoring session data and need both a categorical frequency breakdown by group and a linear/rank correlation between two numeric measures in a single low-cost call. It is ideal for education analytics pipelines where you want quick descriptive stats without setting up a data warehouse. At $0.01 USDC for two reports on up to 200 rows, it is cost-effective for lightweight per-batch analysis. Prefer alternatives if you need predictions, external data enrichment, more than 200 rows, or more than two analytical report types.
Side effects
- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, course_group, date, session_minutes, session_count) cause validation errors
- Null values in session_minutes or session_count may reduce correlation sample size or produce NaN
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Empty rows array returns no meaningful output
