A Series of Tutorials for Teaching Statistical Concepts in an Introductory Course. I. Sampling From an Aerial Photograph.

This paper outlines one of a series of tutorials developed as part of an introductory statistics course for Agricultural and Natural Resource Sciences students. Here we compare two methods of sampling from an aerial photograph to obtain an estimate of the proportion of a particular type of vegetation. One method, transect sampling, is traditionally used by field ecologists, while the other is simple random sampling in a plane. Preparation details and possible extensions to the tutorial are described.
