Stochastic disappointment

It is certainly well over 20 years since I read, somewhere, that stochastic derives from the Greek word for knucklebone

It seemed to make sense, naming stochastic processes after what must be something like a game of Fives or Jacks

So much teaching of statistics begins with tossing dice

Except it was wrong information. Stochastic comes from the Greek to aim, to guess. Stragalos is the word for knucklebone

All societies have indulged in gambling games, using bones or other objects as primitive 'dice'. In fact, the word stochastic which mathematicians use to describe sequences of chance events derives from the Greek word for knucklebone
