Sampling strategies for A level fieldwork
Introduction
Sampling is used because it is not necessary to collect all of the data to understand what the whole population is like.
For example, in a sand dune ecosystem we might be interested in the types of plants growing in each zone of the sand dune ecosystem. The population in this example is all of the plants in the ecosystem. To understand the whole population we sample some plants in each zone. The key is to understand how this can be done reliably and accurately so that the sample is representative of the whole population.
In this clear and informative presentation, fieldwork expert Andy Owen considers the various sampling techniques that can be used by students engaged in geographical fieldwork.
