Our first test will cover Chapters 1, 2, and 3 of our text.

A student asked which graphs you need to be able to work with. The answer is, all of the ones in the computer graphics assignment. You will be asked both to create graphs and to interpret data shown in graphs.

You will also be asked, once for all time, to show in detail how to calculate the standard deviation of a small data set. You should create columns x, x - mu, (x - mu)^2 and totals as shown in class. Naturally, you can check your work with a calculator.

You should expect to give examples of terms that were defined in class, to perform calculations beyond those mentioned here, and to reason about everything that we have talked about in class in the past three weeks.
