EPQ Extraversion Subscore Calculator
Qualified caller-instrument aggregation for EPQ Extraversion Subscore Calculator. Actual separately validated EPQ Extraversion Subscore Calculator key, administration and missing-item policy; no published/proprietary item wording reproduced. Actual verified edition/item bounds/reverse keys/weights required, examples not the published key. Unknown items retain possible-total bounds; no licensed questionnaire reproduced, automatic scoring-key inference, norm, diagnosis, clinical cutoff or validated prediction.
Description
EPQ extraversion scoring requires the applicable edition and item key.
EPQ extraversion scoring requires the applicable edition and item key.1
Aggregation uses verified annotations rather than inferring traits from unrelated records. This tool aggregates a caller-specified scoring key and preserves unknown-item bounds.
When to use EPQ Extraversion Subscore Calculator
Aggregate independently established item evidence using an applicable scoring key, while retaining the range allowed by missing evidence.
How to use EPQ Extraversion Subscore Calculator and how it works
- Establish the instrument edition, administration context, bounds, reverse keys, weights and missing-item policy.
- Enter source metadata and aligned item arrays; mark unknown evidence with 0 and provide valid bounded placeholders, then run the tool.
- Read the known weighted sum, possible-total bounds and unknown item IDs.
- Resolve missing evidence or correct rejected codes before applying the instrument interpretation; a partial sum alone is not a complete score.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedSource | Independently verified source identifier or edition; nonblank, at most 1024 characters. | string | Required; other constraints below |
| callerVerifiedContext | Applicability context, such as equipment, population, units, jurisdiction or protocol; nonblank, at most 1024 characters. | string | Required; other constraints below |
| callerVerifiedAsOfDate | Caller-declared as-of date; real YYYY-MM-DD calendar date in years 0001–9999. This is not automatically a retrieval or freshness date. | string | Required; other constraints below |
| actualInstrumentItemIds | Distinct nonblank IDs for items in the independently verified scoring key. | array of string | Required; other constraints below |
| actualIndependentlyEstablishedItemScores | Observed item codes or valid bounded placeholders for unknown items, in item order. | array of number | Required; other constraints below |
| callerVerifiedItemMinima | Finite lower score endpoint for every item; strictly below its maximum. | array of number | Required; other constraints below |
| callerVerifiedItemMaxima | Finite upper score endpoint for every item, inclusive for codes. | array of number | Required; other constraints below |
| callerVerifiedReverseKeyFlags | Binary flags: 1 reflects a known score around minimum+maximum; 0 leaves it unchanged. | array of number | Required; other constraints below |
| callerVerifiedItemWeights | Nonnegative finite item weights with at least one positive weight. | array of number | Required; other constraints below |
| itemEvidenceKnownFlags | Binary flags: 1 is known evidence, 0 preserves the possible score range instead of using the placeholder. | array of number | Required; other constraints below |
Supply verified source, context and real Gregorian as-of date (YYYY-MM-DD, years 0001–9999), then aligned nonempty unique item IDs, scores, minima, maxima, reverse-key flags, weights and evidence-known flags. Reverse and known flags must be binary; weights nonnegative with at least one positive. Each minimum must be strictly below its maximum, and every score, including unknown placeholders, must lie within its item bounds. Reverse known scores as minimum+maximum-score, multiply by weights, and sum known contributions. Add unknown-item weighted minima or maxima for the possible-total bounds; unknown placeholders never contribute as observed evidence. Return known weighted sum, minimum and maximum possible totals, and unknown IDs in input order. The tool does not supply item wording, a scoring key, norms, questionnaire administration or a missing-item policy.
knownSum=sum(weight*known*(reverse?min+max-score:score)); lower=knownSum+sum(weight*(1-known)*min); upper=knownSum+sum(weight*(1-known)*max) Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.knownWeightedItemSum | Weighted sum of known, reverse-coded where specified, item contributions. | number |
| result.minimumPossibleWeightedTotal | Known sum plus weighted lower endpoints for unknown items. | number |
| result.maximumPossibleWeightedTotal | Known sum plus weighted upper endpoints for unknown items. | number |
| result.unknownItemIds | Unknown item IDs in original input order. | array |

}Limitations and assumptions
The item key and edition come from the caller. The tool neither reproduces a questionnaire nor establishes norms, a clinical diagnosis or a universally meaningful score. Possible-total bounds are arithmetic ranges, not confidence intervals.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
