Simpson's paradox - Wikipedia, the free encyclopedia en.wikipedia.org
"Simpson's paradox, or the Yule–Simpson effect, is a paradox in probability and statistics, in which a trend that appears in different groups of data disappears or reverses when these groups are combined. It is sometimes given the impersonal title reversal paradox or amalgamation paradox. This result is often encountered in social-science and medical-science statistics, and is particularly confounding when frequency data are unduly given causal interpretations. Simpson's paradox disappears when causal relations are brought into consideration. Many statisticians believe that the mainstream public should be informed of the counter-intuitive results in statistics such as Simpson's paradox." -- Super interesting. The Berkeley 1973 sexism lawsuit is a perfect example to understand this. #statistics #paradox #probability #science #data #bias #contrary_to_common_sense #@references #@memorize #interesting #from #delicious #pub
