Document Summary

Mixed methods: compare and contrast the four major qualitative research methods, explain the basic mixed methods research designs, explain the major types of validity in mixed methods research. Week 12: decision-making framework: describe the di erent steps involved in designing a research project, apply the decision making framework to hypothetical and real world examples. Science is a very important way of acquiring knowledge. It is designed to systematically produce reliable and valid knowledge about the natural world. It continues to develop and continue over time. Induction is speci c to general reasoning: aristotle (384-322 bce, still used today when generalizing from speci c experiments to general hypotheses or theory, latan (1981) Observed people do not exert as much e ort in a group as they do working alone \ Inferred that this represents the more general construct of social loa ng: researchers relying on a sample to represent a population.
