About BioStat Lab
BioStat Lab is a precise, offline statistical power and sample size calculator designed for biomedical researchers, clinicians, and students.
CALCULATORS INCLUDED
t-Test — Independent & Paired
Calculate the required sample size for independent-samples or paired t-tests. Enter mean difference, standard deviation, significance level (α), and desired power (1−β).
ANOVA — One-Way
Determine per-group and total sample size for a one-way ANOVA across 2–20 groups. Uses Bonferroni-adjusted alpha for multiple-comparison control.
Proportions — Two-Proportion z-Test
Compare two event rates or response proportions. Displays absolute difference and risk ratio alongside the required sample size per group.
Correlation — Pearson r
Sample size for testing whether a Pearson correlation is significantly different from zero. Uses Fisher z-transformation for accuracy. Includes Cohen's effect-size classification.
Survival — Log-Rank Test
Event-driven sample size for survival studies using Freedman's formula. Enter hazard ratio, expected event rate, α, and power to get required events and total subjects.
DESIGN PHILOSOPHY
Dark space-inspired interface — deep indigo background, violet accent readouts, monospaced numeric displays — optimized for focused scientific work.
PRIVACY
No account required. No data collected. All calculations happen on-device.
