A statistics test for 8th grade math test prep: mean, median and range, how an outlier changes them, probability of simple and compound events (number cubes, coins, marbles, raffles), counting outcomes, associations in scatter plots, and speed, distance and time. The questions take the forms of end-of-year state math tests: multiple choice, true or false, and open-response problems with room to show the work.
