My daughter is an accountant. She took a statistics class in high school, and another as a requirement for her major. My son has taken a statistics course, and he is an English Literature major. I was a chemistry major in college and have an an MD and have never taken a statistics course. I don’t even recall a lecture on statistics in medical school. Mark Twain quoted Disraili as saying, “There are three kinds of lies: lies, damned lies and statistics.” Reading medical journal articles reporting on the benefits and lack of benefits when reported statistically can be really challenging. Reading a report of these, or worse listening to an interested party, like a sales rep or sponsored speaker talk about a study, requires being a skeptic. Here are some examples of how true statistics can be worse than a lie, and how what would seem to be common sense does not pay off.
