The course focuses on practical application of sampling strategies, and the effects of sound versus inappropriate sampling approaches on conclusions drawn from evaluation results. The course is intentionally interactive, with opportunity to work in small groups on case exercises. The content focus of this course includes: a) defining the sampling frame – linkage to evaluation questions to be addressed; b) sampling methods – probability (random, systematic, clusters, stratified), non-probability (convenience, quota, snowball, judgmental) samples, and multi-phase/stage sampling; c) sample size and sampling error; d) response rates; e) interpreting evaluation results using samples – how sampling strategies affect evaluation validity; f) sampling issues and considerations. Case examples will be provided.
