Statistics · epidemiology · the maths underneath
Clearstistics explains statistics, epidemiology and the maths behind them — one concept at a time, in plain English, with visuals that do the explaining. No formulas thrown at you, no prior knowledge assumed.
Newest first. Every video stands on its own, but they also build on each other — new here? Start with video 1. Subtitles are on the YouTube player (the CC button).
A YouTube channel about statistics and methodology — with an epidemiological slant — and the maths that sits underneath. Made for students, researchers brushing up, and anyone trying to read a scientific paper without getting lost.
The building blocks: the normal distribution, mean, median and mode, standard deviation and standard error, confidence intervals and p-values. And the methods behind medical research: relative risk, odds ratios, survival analysis and the models that sit underneath them.
Every chart is drawn in code, straight from the numbers — so what you see on screen is what was actually computed, not an illustration of it. Greek letters always come with their name (μ is “mu”, σ is “sigma”), and every spoken number is checked against what's in the picture before a video goes out.
The same idea always wears the same colour, so once you've seen it once you'll recognise it everywhere:
mean μ (mu) spread σ (sigma) median & uncertainty mode highlight error

Not medical advice. Clearstistics explains how numbers are calculated and read. It says nothing about what you should do about your own health — for that, talk to a qualified professional.
