Joining datasets is where multi-source analysis gains most of its value and picks up most of its errors. Here is what each join type keeps, why grain matters, how fan-out inflates totals and test statistics, how key mismatches drop records without warning, and a five-check routine to verify any join before it feeds a decision.
A live QuantumLayers demo: we pulled every earthquake the USGS recorded over 30 days — 10,877 of them — into a public dataset and charted what the planet has been doing beneath our feet.
