Inferential Analysis and Interpretation

This chapter builds on the concepts related to project design (Chap. 5 ) and descriptive statistics (Chap. 6 ) to present a number of possible inferential statistics approaches suitable for the Problem-Intervention-Outcome Meta-Model (PIO MM) (this chapter) to better understand the practical and statistical significance of the data. Interpretation of the analysis is discussed for each of the inferential methods. Selecting appropriate inferential statistics depends on your project study design, the variables representing the PIO MM concepts, and the measures used to operationalize them.
