It's everybody's favorite time of year: the time in AP Psychology class where we closely examine how descriptive statistics (particularly, standard deviation and z-scores) help us make sense of test data.
To help with practice on basic descriptive statistics, students should complete this PsychSim Module on Descriptive Stats. Lost the worksheet you got in class? You can print another one here. Just note that it is two pages, so be sure to complete/print both sides.
Still lost when it comes to normal distributions, z-scores, and percentile ranks? You might wish to review this video from a fellow AP Psych teacher, who has posted it to help you with your review.
