II-c Sampling Techniques for Development Evaluation I
This workshop focuses on the use of sampling to improve the quality and efficiency of development evaluations. Starting with the three pillars of every evaluation, the workshop places sampling techniques at their rightful place in the design pillar. It then clarifies the difference between qualitative and quantitative evaluation approaches as related to sampling techniques. The workshop addresses common myths about sampling, explains various types of random and purposeful samples, notes the advantages and disadvantages of each, develops participant skills in drawing several types of samples, and discusses how to determine needed sample sizes. Web-based tools and widely-available software are introduced. Participants practice skills throughout the various sessions. In small groups, they also work through many complex case studies. The treatment of the topic is conceptual, rather than mathematical, and knowledge of statistics is not required.
