How this service works
Question bank coverage — Numeric interval filter + Secondary-measure weighted mean: Numeric interval filter + Secondary-measure weighted mean 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: one showing the subset of input rows where the chosen field (item_count or objective_count) falls within the specified [minimum, maximum] interval, and one with the secondary-measure weighted mean computed across those filtered records. Output covers up to 200 input rows and is computed entirely from supplied data with no external lookups.
Example use cases
Curriculum coverage gap analysis
“I've got question bank data for groups A through D across October — filter all rows where item_count falls between 10 and 100, and give me the weighted mean of objective_count for what remains.”
Outlier exclusion before reporting
“Before our weekly report, filter out any rows where objective_count is outside the 2 to 30 range, then compute the weighted mean of item_count for the remaining course coverage records — I have about 80 rows to process.”
Course group balance check
“Can you take my 60 question bank coverage rows, filter to only those where item_count is between 0 and 25, and calculate the secondary-measure weighted mean of objective_count so I can see if course groups are balanced?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-education-18-132?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 question bank coverage records (with item_count and objective_count fields) and need both a numeric interval filter on one measure and a weighted mean of the secondary measure in a single call. It is well-suited for education analytics pipelines where you want to exclude out-of-range records and immediately summarize the filtered set, all from supplied data without any live data lookup or external dependency.
Side effects
- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- minimum greater than maximum — may return empty filtered set with no weighted mean
- Null values in the measure field — may affect weighted mean calculation or be excluded
- Missing required row fields (row_id, course_group, date) — validation error
