Central Limit Theorem Simulator
Watch skew become normal
Sample from uniform, skewed or bimodal populations and watch the distribution of sample means pile up into a bell curve with SD σ/√n.
Scored investigations
Playing with a simulation is not the same as earning a point. These take your own measurements from this lab into a real AP free response, graded against the rubric.
