AP Statistics: AP Statistics – Measures of Center, Spread, and Shape Quiz

The familiar measures of center (mean, median, mode) and spread (range, standard deviation, variance, and interquartile range) will generally not be directly tested on the AP exam, because you can determine these so easily on your calculator. Instead, you will have to manipulate or interpret these values in some meaningful way. Questions about the shape of a distribution will rely on your familiarity with the effect of outliers on data, if any, and on your general knowledge of the shape of normal, uniform and bimodal distributions. Knowledge of skewness (right-skewed or left-skewed) is of critical
importance.
