PBS Math Club S01 E07 Mean (Averages) & The Math of Texts

Ever have that friend who OBSESSES over the meaning of EVERY text message? It can get real dramatic. At Math Club, we have a "secret mean" to help take the drama out of dating. What is this "secret" mean you ask? It's nothing more than an average, or the sum of a list of numbers divided by the size of the list. Mean: or as we call it, "life's highs and lows AVERAGED out."
