Data has a story. We find the ending.

Real clinical data. A real regression model. A real p-value that decides whether your blood pressure prediction is statistically meaningful — or just noise. Follow along step by step.

Workshop

The math is right. Prove it with code.

Translating intuition into a working hypothesis test is where most students get lost. The Workshop gives you a live Python environment to run the actual test — import scipy, compute the p-value, and see the statistics speak.
