Methods in EEC (BIO 221B) Dr. Jim Baxter Spring 2014 Dept. of Biological Sciences 1 Vegetation Sampling Using the Quadrat Method A quadrat is a frame that is laid down to mark out a specific area of the community to be sampled. Within the quadrat frame, the occurrence of plants is recorded using an appropriate measure of abundance. Quadrats may be square, rectangular or circular and they may
Non-probability sampling focuses on sampling techniques that are based on the judgement of the researcher [see our article Non-probability sampling to learn more about non-probability sampling]. This article explains (a) what snowball sampling is, (b) how to create a snowball sample, and (c) the advantages and disadvantages (limitations) of snowball sampling.
Understand how each selected sampling method works, the differences between the methods, and the advantages & disadvantages of each method. Plan a hypothesis and predictions that follow logically from the hypothesis, and discuss the ideas with the TA …

measure relevant factors and what research techniques such as questionnaires or experiments to be employed (Neuman, 2006: 14). In addition, quantitative methods characteristically refer to standardized questionnaires that are administered to individuals or households, which are identified through various forms of sampling usually random sampling (Dudwick, Kuehnast, Jones and Woolcock, 2006: 3
Sampling techniques may be used to find representative samples to avoid bias. In practice, the sample size that is selected for a study can have a significant impact on the qualityof your results/findings, with sample sizes that are either too small or excessively large both potentially leading to incorrect findings.

Quadrat sampling is not useful for studying very fast-moving animals who will not stay within the quadrat boundaries. In general, quadrat sampling is less harmful to most species when compared with other methods- so long as the study occurs in the field.
