This chapter walks the reader through the major strengths and limitations of qualitative and quantitative research designs to facilitate choosing a methodology that allows for research questions to be answered effectively. Mixed-methods research is briefly discussed, with resources for more information. Sampling methods appropriate for each paradigm are discussed and compared to help readers select the appropriate method for their situation. The issue of obtaining a representative sample is also discussed in the context of random sampling. Probabilistic and non-probabilistic sampling methods are differentiated, along with detailed discussion of simple random sampling, cluster sampling, stratified sampling, systematic sampling, purposeful sampling, and convenience sampling.
