Description
Return response share with a zero-opportunity flag.
Behavioral-study coding depends on observation intervals, missing samples, event records and assignment rules. Partial-, whole- and momentary-sampling summaries answer different questions; local agreement or coverage does not establish actual behavior, a diagnosis or an effective intervention.
Return response share with a zero-opportunity flag.
When to use this tool
Use Response Opportunity Zero Denominator when checking the stated behavioral-research observation, assignment, coverage or coding convention.
How to use the tool and how it works
- Enter responses, opportunities. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read defined, share. Inspect defined before interpreting the associated values.
Return response share with a zero-opportunity flag. Require nonnegative whole opportunities and responses within it; share = responses/opportunities or zero with defined false when none.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| responses | Responses | Required. Safe integer; minimum 0. |
| opportunities | Opportunities | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| defined | Whether the stated denominator or information basis supports this value; inspect placeholders before interpretation. | Required. Boolean. |
| share | Dimensionless numerator/denominator ratio under the explicit basis above. | Required. Finite number. |

}Limitations and assumptions
- The zero placeholder is not observed zero response probability; no behavioral interpretation or sampling inference is provided.
- 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 verified observations and the study’s complete sampling/coding protocol, with appropriate statistical and professional interpretation for health or intervention decisions.
