Chapter 8 – Sampling issues in research. In this chapter students will be able to: Explain the reasons for sampling, distinguish between probability and non-probability sampling methods, select an appropriate sampling procedure, explain the types of sampling bias, avoid sampling bias in your research designs now and in the future. | Planning an Applied Research Project Chapter 8 – Sampling Issues in Research © 2014 John Wiley & Sons, Inc.
