The sample from a population applet lets the user select samples of various sizes from a wide range of population shapes including uniform, bell-shaped, skewed, and binary populations (including a range of values for the population proportion, p ). In addition, one can alter any of the default populations to create a custom distribution by dragging the mouse over the population or by going to Custom binary and typing in the desired population proportion. Small samples are drawn in an animated fashion to help students understand the basic idea of sampling. Larger samples are drawn in an unanimated fashion so that characteristics of larger samples can be quickly compared to population characteristic.
