Pick any of the 8 distributions representing the "parent population" (with values in the range 0 - 100) by clicking the corresponding radio-button, then select the size N of the population sample (N = 1-30) by pressing the buttons "Inc" (increase) / "Dec" (decrease). By pressing the "DRAW" button, the histogram representing the distribution of the generated population starts to be drawn. Obviously for N = 1, the histogram of the "parent population" will be obtained.
The relative population size used for the creation of the histogram can be selected by clicking one of the radio-buttons labelled "Small", "Medium", and "Large". The larger the size of this population is, the less jagged this histogram will appear, but it will take more time to be completed.

Glossary
histogram
A statistical diagram for continuous data similar to a bar chart but where the area of each bar is proportional to the frequency.
population
A collection, group or set of individuals or objects.
range
In Statistics: the difference between the largest and smallest values in a data set; a simple measure of spread or variation
In Pure Maths: the values that y can take given an equation y=f(x) and a domain for x.
