Title: SCIENTIFIC RESEARCH CYCLE (Jim Nelson)
1SCIENTIFIC RESEARCH CYCLE (Jim Nelson)
Data How to get it? What do with it?
Theory/model built on the data
Hypothesis suggested by the theory and data
Inductive Reasoning
Deductive Reasoning
Where do you jump into the cycle?
The answer depends on the nature of the research
2INDUCTIVE REASONING (Leedy, p.33)
- Begin with the data
- Asking what does this mean
- Build or adopt and modify a theory (good idea) or
model - Comes from a specific context
- Inductive reasoning
- A reasoning process of drawing conclusions from
facts or circumstances. Reaching generalizable
conclusionsoften qualitative research to derive
meaning from within a context
3RESEARCH CYCLE (cont.)
- Inductive Reasoning Recognizes . . .
- The meaning of data in context Validity (whats
going on here? A search for truth) - Focus is on understanding the perspective in a
particular context - Effective Methods Participant observation,
interviews, focus groups case studies - --Context dependent
4DEDUCTIVE REASONING (Leedy,9. 32)
- State an hypothesis and test it
- Does this work?
- Can I predict or anticipate certain things as a
result of what I know - Knowing x and y, can I predict z?
- Hypothesis represents a viewpoint and you are
controlling the data - A process of logical reasoning from stated
propositions. Hypothesis testingoften
quantitative research, based on numbers -
5RESEARCH CYCLE (cont.)
- Deductive Reasoning Requires
- Quantification and measurement Reliability
(consistency). - Focus is on prediction and control
- Effective Methods survey, random sampling, means
to verify hypothesis quantification - --Researcher dependent
