Description
Descriptive research repeatability relative to a supplied instrument resolution, without a pediatric reference range.
Pediatric research records use chronological age, visit windows, measurement resolution, task observations, and caregiver reports. Missing observation differs from noncompletion, and a completeness share depends on its denominator. Arithmetic on supplied records is separate from a developmental or clinical assessment.
Descriptive research repeatability relative to a supplied instrument resolution, without a pediatric reference range.
When to use this tool
Use Pediatric Measurement Repeat Range Term when you need this age, observation, visit, measurement, or record-completeness calculation with supplied inputs.
How to use the tool and how it works
- Enter measurements, resolution. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read mean, range, rangeInResolutionUnits. Use the output convention below.
For a nonempty measurements list and positive resolution return arithmetic mean, range=max-min, and rangeInResolutionUnits=range/resolution.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| measurements | Measurements | Required. Array of finite number; maximum items 256. |
| resolution | Resolution | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| mean | Mean | Required. Finite number. |
| range | Range | Required. Finite number. |
| rangeInResolutionUnits | Range In Resolution Units | Required. Finite number. |

}Limitations and assumptions
- Measurements and resolution need one unit. A one-value sample has range zero; repeat range does not estimate all measurement error, establish a confidence interval, or assess a child's health.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use verified dates, measurement protocols, and observation definitions for the intended research question. A clinical interpretation needs the relevant age-specific assessment and context beyond the arithmetic record check.
