FYI: In 1733 Abraham de Moivre, drawing on the work of Jacob and Nicolaus Bernoulli, calculus, and the underlying structure of Pascal's Triangle, demonstrated how a set of random drawings would distribute themselves around their average value. De Moivre's distribution is know today as a normal curve. It makes it possible to evaluate the probability that a given number of observations will fall within some specified bound around a true ratio.

3) **Review for Friday's Quiz**. Study your class notes (concepts/vocab), assignments,
and review Chapters 4 and 5 of our book (you can ignore Re-expressing Data pgs
89-91). The quiz will focus primarily on displaying quantitative data and describing
distributions numerically but everything covered so far is fair game.

For those interested: Why divide by n-1

Challenge: Use calculus to prove that the mean is the minimum for the sum of the squared deviations from the mean.
