Using a given list of four complex numbers, find by inspection the one that is a root of a given cubic real polynomial and hence find the other roots.

Students are shown a normal distribution, and a slider that moves the distribution horizontally. They are asked to move it so that the mean is equal to a particular value.

Students are shown an unsorted list of 6 or 7 numbers and asked to calculate the median.

A normal curve is displayed. Mean and standard deviation can be set by sliders.
