So when looking at sampled data, ask yourself what is the sample representing?ĭifferent types of average needs to be correctly understood: The sample with the built-in biasĮvery sample have a built-in bias, the people that gets the survey, the people that answers the survey, the emotional impact of the interviewers on the interviewee, the way the questions are asked. It is a super easy read and I strongly recommend it to any people interested in refreshing their statistical science (not math) knowledge. First, it is easier to identify statistical bias (conscious or unconscious), secondly it helps asking the right questions when presented with graphs or numbers, lastly it helps presenting and comprehending correctly hypothesis done day to day. Understanding the science behind statistics can helps us in multiple ways. Written by Darrell Huff in 1954, the book was extremely refreshing (the tone used in the book is illustrative of a mindset that we seem to have lost). I decided to use the thanksgiving break time to read it. Just before the thanksgiving break, I attended to a book club event (internal to Bing) and Scott Berkun advised to read the book “How to lie with statistics”.
