Enter your sample stats, hit “Calculate,” and the tool instantly returns the test-statistic and p-value; 85 % of biomedical papers use the 0.05 alpha threshold (Curran-Everett, 2017).
The calculator lets you plug sample numbers into Z-, t- or χ²-formulas and instantly returns the p-value so you can accept or reject your hypothesis. For example, entering X̄ = 102, μ₀ = 100, σ = 8 and n = 64 yields p ≈ 0.045, just above the standard 0.05 cutoff used in 79 % of scientific papers (Head et al., 2015).
