Many Books ... Same Ideas

I read the first two chapters in a couple of research methods books I bought last semester. I have looked at the opening chapters of 4 books so far and find that all of them present very similar ideas. They define a theory, they define research, and they divide research in applied and basic (or pure). They describe the process of conducting research and its defining characteristics. Sekaran presents the defining characteristics of research as:
1. Purposiveness – having a definite aim or purpose,
2. Rigor – having “a good theoretical base and a sound methodological design”,
3. Testability – analytically applied to a hypothesis,
4. Replicability – able to be duplicated by other researchers and leading to the same conclusions,
5. Precision and Confidence – results closely replicate the real world and contains a high probability of being correct,
6. Objectivity – based on the facts uncovered and not on the subjective biases of the researcher,
7. Generalizability – can be applied to larger populations or situations than were used for the study, and
8. Parsimony – explains the research and its results in a manner that is clear and understandable to a larger audience.
