Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

correlation

Two things tending to vary together.

Two factors are correlated when higher (or lower) values of one tend to go with higher (or lower) values of the other. A correlation can come from one causing the other, from a common cause, from the cause running in the opposite direction, or from coincidence.

Examples

  • Across towns, the number of fire trucks sent to a fire is correlated with the damage done; bigger fires cause both.
