Lorraine Huff Unit 3 Discussion Board February 28, 2010 “Sampling is the process of selecting units from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen.” Simple random sampling is the basic sampling technique where we select a group of subjects for study from a larger group. Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample. Every possible sample of a given size has the same chance of selection. An example of simple random sampling can be seen in the Coke vs. Pepsi taste test challenge. This challenge determines whether or not people are able to correctly identify the difference in taste in the two different colas by giving a blind taste test. The first part of the experiment is where researchers conduct the experiment. In the second part, researchers use the simple random sampling method to gather data on what would be expected under chance
