Where does the Bell Curve come from?
Speaker: Chris Jackson
Everyone has heard of the ‘bell curve.’ Sports show hosts, teachers, scientists and a bunch of other people routinely use the term ‘bell curve’ to describe uncertainty. But do you know where it comes from? It is not just a ‘pretty shape’ that seems to work, It comes from a really cool physical phenomena that we find everywhere. So the ‘bell curve’ naturally aligns with how our primitive human brain often tries to characterize or visualize uncertainty. The other really cool thing about the bell curve (and lots of other curves that look like bells) is that if we find it in our reliability data, it automatically tells us where to look in order to improve reliability. If you want a basic introduction to one of the most common statistical concepts with NO EQUATIONS … this is the webinar for you!
