In each of the following exercises, identify the type of sampling to which the premise refers: random, systematic, convenience, stratified, by cluster: a) The sample is homogeneous and results are as accurate as simple random sampling, but with a smaller sample size. b) It tends to provide better results when the elements within the clusters are not similar. c) A professor conducting research at a university may use student volunteers to constitute a sample simply because he has them available.
