THE NUMBERS, EXPLAINED
How to use this calculator.
Binary independent decisions on the same records. Agreement is observed percentage; no chance correction or adjudication is implied.
Start with your inputs
Enter reviewer a inclusion decisions (0 exclude, 1 include), reviewer b inclusion decisions (0 exclude, 1 include). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Reviewer A inclusion decisions (0 exclude, 1 include) | 1,0,1,0 |
| Reviewer B inclusion decisions (0 exclude, 1 include) | 1,1,0,0 |
A worked example
With the example inputs above, observed agreement (%) is 50. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Observed agreement (%) | 50 |
| Adjudication row numbers | 2, 3 |
| Conflict count | 2 |
How this is calculated
Observed agreement (%)
Divide matching decisions by all records.
Adjudication row numbers
List records with conflicting decisions.
Conflict count
Count mismatched paired decisions.
Symbols and units
- a
- Reviewer A inclusion decisions (0 exclude, 1 include)
- b
- Reviewer B inclusion decisions (0 exclude, 1 include)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Binary independent decisions on the same records. Agreement is observed percentage; no chance correction or adjudication is implied.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Observed agreement (%); Adjudication row numbers; Conflict count. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Binary independent decisions on the same records. Agreement is observed percentage; no chance correction or adjudication is implied.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
