Description
Calculate supplied session minutes weighted by exposure fraction.
Behavioral records distinguish observed outcomes, missing observations, response deadlines, code conflicts and sampling opportunities. Unobserved trials differ from observed wrong responses, while time coverage differs from event probability. Supplied observations and cutoff values do not by themselves validate a task or identify a behavioral mechanism.
Calculate supplied session minutes weighted by exposure fraction.
When to use this tool
Use Intervention Exposure Minute Contribution when you already have sessionMinutes, exposedFraction and need to calculate supplied session minutes weighted by exposure fraction.
How to use the tool and how it works
- Enter sessionMinutes, exposedFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read exposureMinutes. Use the output convention below.
Require sessionMinutes>=0 and exposedFraction in [0,1]; multiply them.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| sessionMinutes | Session Minutes | Required. Finite number; minimum 0. |
| exposedFraction | Exposed Fraction | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| exposureMinutes | Exposure Minutes | Required. Finite number. |

}Limitations and assumptions
- This weighted nominal exposure is not verified attendance, intervention fidelity, dose, effectiveness or suitable support.
- 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 the complete protocol, observation records and analysis plan. Check missingness, coding rules, timing and sampling design before interpreting local counts, labels or interval fractions as research outcomes or appropriate interventions.
