Diverse theories, actions, and sets of evidence from a range of professional and disciplinary perspectives are included to underscore the importance of integrating evaluation and practice in research.
[Page 248]The primary objective of this chapter is to discuss methods of analyses across all three traditions as they are most useful throughout examined practice. We begin with experimental-type design, identifying the logic of choosing a statistical approach. The action processes of statistical calculation central to experimental-type inquiry are then discussed before we move on to analysis in naturalistic inquiry and mixed methods.
What Is Statistical Analysis?
A formal definition of statistical analysis is the organization, interpretation, and presentation of data according to well-defined, systematic, and mathematical procedures and rules (DePoy & Gitlin, 2016). As discussed in Chapter 11, the term data within the experimental-type tradition refers to information obtained through measurement, answering questions such as, “How much? How many? How long? How fast? How ...
