The Data Lie

Data does not lie. But people who collect, interpret, and present data? They lie constantly. Sometimes deliberately. Usually by accident. The Data Lie is a wake-up call for every manager, marketer, and entrepreneur who has ever made a decision based on a spreadsheet. Statistician Dr. Priya Mehta spent fifteen years watching companies make catastrophic choices based on flawed metrics. She has seen a billion-dollar brand change its entire strategy based on a typo. She has seen a startup raise £10 million on a dashboard that measured the wrong thing entirely. This book teaches you how to spot the lies hidden in your own reports: sampling bias, correlation confusion, cherry-picked timelines, and the single most dangerous phrase in business — “the data speaks for itself.” Your data is speaking. But is it telling the truth? Learn to ask the right questions before you trust the numbers.
