Calculated result
When to use
Test whether an observed binary event count differs from a hypothesized probability.
Formula or algorithm
Exact binomial probabilities are summed from Binomial(n, p0) according to the selected alternative.
Assumptions and limits
Use the variable scales and sampling design required by this named statistical method. Review missing values, independence or pairing, outliers, and distribution or model assumptions before interpretation. Confirm that the selected dependent, independent, grouping, time, item, rater, or matrix variables match the research design.

Data Import and Variable Requirements
Upload XLSX, CSV, TSV, TXT, JSON, or pasted data where applicable; inspect cleaning, select the required variable roles, and review mapped inputs before calculation. For Exact Binomial Test Calculator, map Observed successes, Total trials, Null event probability, Alternative, Alpha from the cleaned browser-local table; every mapped variable remains editable before calculation, and the active dataset remains available while you work with this selected test and when you return to the Test Finder.
Uploaded files are processed locally in the browser. The cleaning report appears before variable selection, and the selected cleaned columns are mapped to this exact calculator rather than a generic fallback.

Required Inputs
- Observed successes (required)
- Total trials (required)
- Null event probability (required)
- Alternative (required) Options: Two-sided, Greater, Less
- Alpha (required)
Results Reported
The result workspace shows the final answer and intermediate quantities needed to audit the calculation. Depending on the method, reported values include:

How to Use This Workspace
- Confirm that the method matches the quantity, hypothesis, model or planning question you need to solve.
- Enter values with compatible units and the requested sample, group, matrix, count, date or option format.
- Use Example Data to inspect a valid input layout, or enter your own values and run the calculation.
- Review the result table, formula, substitutions, warnings and interpretation rather than relying only on the headline number.
- Copy, download or print the result when you need a reusable analysis record.
Understanding and Reporting the Result
Interpret the estimate, uncertainty, test statistic, p-value, effect size, and diagnostics for the selected variables and design. In the Exact Binomial Test Calculator result workspace, interpret Observed Proportion, Exact P Value, Decision together with the method assumptions, warning messages, confidence information, effect magnitude, and diagnostic plots shown for the selected variables.
Enter counts rather than percentages and review expected-frequency warnings; sparse 2x2 tables may require Fisher exact inference.
Keep the entered values, units, selected options and any warning shown beside the result. For a hypothesis test, report the statistic, degrees of freedom where applicable, p-value, alpha level, effect size and decision. For an estimate or conversion, report the formula convention and final unit.
How to Report the Result
Report the method, selected variables, sample information, estimate or statistic, uncertainty, p-value when applicable, and practical conclusion. A reproducible Exact Binomial Test Calculator report should identify the mapped variables, valid observations, exclusions or missing-data handling, selected options, principal outputs, uncertainty, diagnostics, and the practical conclusion supported by the analysis.
Accuracy and Limitations
The calculator keeps full browser precision during calculation and rounds only for display. Accuracy still depends on correct inputs and on whether the displayed model represents the real problem. Educational calculators cannot replace required professional review, current official rules, field measurements, laboratory methods or specialist statistical software where those are necessary.
