Statistics and Lies

Found this (little old) story linked from a group.

2 divorces for every 5 knots in Mumbai

This headline claims that a staggering 40% marriages end up in divorce. Here is their methodology. Count the number of weddings registered in last five years. Count the number of divorce cases filed in last five years. Compare them. Tada!

After reading the article, any person with IQ of mid-to-high double digits can figure out that sample set used in both cases is different. They should have counted the divorce cases filed where the couples were married during the period under observations. Well, then those facts would not have been so sensational. Somebody rightly said, media sells sensationalism, not news, definitely not facts.
