Nominated for the getAbstract International Book Award 2015. In modern life, there are more numbers than words. Big Data is on everyone's lips. But data must be interpreted just like words in order to be understood. Math professor and number guru Christian Hesse shows how. He reveals the most significant sources of error in numbers, data, and statistics, explains how they arise, and how to remedy the situation. One might think that numbers don’t lie. However, this is not always true. One can draw obvious conclusions from numbers, data, and statistics and still be wrong. This could be called lying with the truth. For example, did you know that your situation could worsen if you are given an additional option? This is just one of many paradoxes relevant to daily life that Christian Hesse's new work addresses.
