📱 eBook en inglés STATISTICAL MIRAGES

We live in an era that worships data. We are told that numbers do not lie and that statistical trends are the ultimate arbiter of truth. But there is a mathematical blind spot so profound that it can legally and statistically prove that a drug cures a disease, even when it actually kills more patients.
This terrifying glitch is known as Simpsons Paradox. It occurs when a clear trend appears in different groups of data, but completely disappears or reverses when those groups are combined. It is the reason why universities have been wrongfully sued for gender bias, why batting averages in baseball make no logical sense, and why clinical trials can be legally manipulated to show whatever the funder desires. By simply aggregating or separating data points, the exact same numbers can tell two completely opposite, mathematically verifiable stories.
This book breaks down the architecture of data manipulation. It exposes how politicians, pharmaceutical companies, and marketing executives weaponize aggregation to obscure reality and engineer consensus without ever technically lying.
You will learn how to dissect the numbers you are fed daily, spot the hidden variables lurking beneath the surface, and immunize yourself against the statistical sleight of hand that dictates modern policy.
