How this service works
Tutoring sessions — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean 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) an equal-width histogram showing bin edges, bin counts, and frequency distribution for the chosen primary field (session_minutes or session_count) across the supplied rows; (2) a secondary-measure weighted mean computed from the same dataset. Both reports are generated locally from supplied data with no external lookups.
Example use cases
Tutoring duration distribution by course group
“I have 80 tutoring session records across math and science groups from last semester — can you build an equal-width histogram on session_minutes with 8 bins and also give me the weighted mean of session_minutes weighted by session_count?”
Session count frequency analysis for reporting
“I need a statistical summary of our tutoring program for the board report — can you compute an equal-width histogram of session_count using 5 bins and a weighted mean for these 150 session records I'll supply?”
Comparing session engagement across date range
“Here are 200 tutoring session rows from Q1, each with date, course_group, session_minutes, and session_count — please run the equal-width histogram on session_count with 6 bins and a secondary weighted mean, so I can see how engagement varied.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-16-172?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 tutoring session records and need both a frequency distribution (histogram) and a weighted mean in a single API call. It is ideal for education analytics pipelines where session_minutes and session_count are the core metrics and no external data enrichment or prediction is needed. It is cost-effective at $0.01 USDC for two reports simultaneously.
Side effects
- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, session_minutes, session_count, date, course_group) cause validation errors
- Invalid date format (non-YYYY-MM-DD) triggers schema rejection
- Bins value outside 1–30 range fails validation
- Null values in primary field may affect histogram bin calculation
- Invalid field enum value (not session_minutes or session_count) causes rejection
