Description
Return task administration and validity fractions on distinct denominators.
Developmental research records may encode task eligibility, known responses, observer roles and withdrawal. A flag or support share describes supplied observations and does not independently assess a child, verify consent or establish a clinical interpretation.
Return task administration and validity fractions on distinct denominators.
When to use this tool
Use Child Task Valid Trial Proportion when checking explicit developmental-study record and observation rules.
How to use the tool and how it works
- Enter scheduled, administered, valid. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read administrationFraction, validOfAdministered, validOfScheduled. Use the output convention below.
Return task administration and validity fractions on distinct denominators. Require whole scheduled >= administered >= 1 and valid in [0,administered]; compute administered/scheduled, valid/administered and valid/scheduled.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| scheduled | Scheduled | Required. Safe integer; minimum 1. |
| administered | Administered | Required. Safe integer; minimum 1. |
| valid | Valid | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| administrationFraction | Administration Fraction | Required. Finite number. |
| validOfAdministered | Valid Of Administered | Required. Finite number. |
| validOfScheduled | Valid trials divided by scheduled trials; differs from validOfAdministered. | Required. Finite number. |

}Limitations and assumptions
- The descriptive fractions do not verify trial quality, participant capacity or developmental competence.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use an approved study protocol and appropriate professional assessment for participant decisions, developmental interpretation or clinical questions.
