Interactive video lesson plan for: Mean (Averages) | The Math of Texts | PBSMathClub

Activity overview:

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."

Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.
