How this service works
Question bank coverage — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation for supplied question bank coverage records (item_count, objective_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 deduplicated set of the input question bank coverage rows with exact duplicates removed, and (2) a Pearson or similar correlation measure between item_count and objective_count across the deduplicated records, computed entirely from the supplied data using local analytical engines with no external lookups.
Example use cases
Curriculum alignment correlation check
“I have coverage data for our question bank across several course groups — can you deduplicate the rows and tell me how strongly item_count correlates with objective_count? I'll send you the records for groups A, B, and C across the last quarter.”
Duplicate question record cleanup
“Our assessment team exported question bank records and there are likely duplicate rows mixed in. Can you run deduplication on these 80 rows and also compute the correlation between the number of items and objectives so I know if they track together?”
Comparative coverage analysis across dates
“I need to compare item counts and objective counts across our course groups from October 2026. Please deduplicate the records first, then give me the correlation report for both measures across the entries.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-18-050?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular question bank coverage data (up to 200 rows) and need both exact duplicate removal and a two-measure correlation analysis between item_count and objective_count in a single low-cost call. Prefer this over general-purpose analytics tools when your data fits the education/assessment domain and you want a lightweight, self-contained computation without external data lookups or predictions.
Side effects
- Input array is empty (minItems:1 violated) — validation error
- More than 200 rows submitted (maxItems:200 violated) — rejected
- Missing required fields (row_id, course_group, date, item_count, objective_count) — validation error
- Date field does not match YYYY-MM-DD pattern — validation error
- item_count or objective_count outside allowed numeric range — validation error
- All rows identical after deduplication — may result in degenerate correlation output
- Insufficient variance in either measure — correlation undefined or returns NaN
