Sampling is a computer tool designed to help biology students obtain a qualitative understanding of basic concepts related to estimation and statistics.

Sampling presents the user with a group of hypothetical populations distributed throughout an area, and with tools for sampling these populations to estimate characteristics such as population size and density, the nature of each population's spatial patterning, and spatial correlations in abundance between populations. By manipulating the number of samples, the size of each sample, and the spatial location and patterning of samples, users of Sampling can investigate important questions in population estimation and, especially in conjunction with field studies, develop a much deeper understanding of fundamental concepts than would likely be obtained solely from limited field studies that can be conducted in introductory courses.
