Biostatistics for Clinical Research
Move beyond basic averages to design rigorous studies and interpret complex medical data. Learn to handle bias, calculate power, and model survival outcomes like a professional researcher.
Like Duolingo, but for Biostatistics for Clinical Research. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through Designing for Discovery, Modeling Relationships, and Interpreting the Evidence. It assumes you already know the basics.

Key ideas in Biostatistics for Clinical Research
- The definition and practical implication of statistical power in a study design
- The clinical danger of Type II errors compared to Type I errors
- Smaller expected differences between groups require much larger sample sizes to detect
- Effect size is estimated from previous literature or clinical relevance standards
- Stricter significance thresholds (lower alpha) make it harder to detect real effects
- Adding participants reduces standard error, which directly boosts the study's power
- The trade-offs between alpha, power, and sample size
- Pilot studies provide an estimate of data variability (standard deviation) for power calculations
- The role of effect size in determining sample size requirements
- Pilot results help test the feasibility of recruitment and protocol adherence
- Pilot studies are underpowered and cannot be used to prove a drug is effective
- The specific purpose of conducting a pilot study in biostatistics
- Randomization distributes both known and unknown confounders equally between groups
- Subjective outcomes are highly susceptible to observer and participant bias
- Statistical balance ensures that differences in outcomes are due to the intervention
- Hard endpoints like mortality are less influenced by the psychological effects of blinding

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Biostatistics for Clinical Research the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If your study is designed to detect a real biological difference that actually exists, what is the technical term for the probability that you will successfully find it?
