Method of Inquiry
As with the research for most case studies, the scientific method is standard. It allows you to use existing knowledge as a starting point. The scientific method has the following steps:
-
Ask a question.
-
Do background research.
-
Formulate a problem
-
Develop/construct a hypothesis.
-
Make predictions, based on the hypothesis.
-
Do experiments to test the hypothesis.
-
Conduct the test/experiment.
-
Analyze and communicate the results.
The above terminology is very similar to the research process. The main difference is that the scientific method is objective, and the research process is subjective. Quantitative research is based on impartial analysis, and qualitative research is based on personal judgment.
Research Method
After selecting the method of inquiry, it is time to decide on a research method. There are two main research methodologies: experimental research and non-experimental research.
Experimental research allows you to control the variables, and to manipulate any of the variables that influence the study.
Non-experimental research allows you to observe, but not intervene. You just observe and then report your findings.
Research Design
The design is the plan for how you will conduct the study, and how you will collect the data. The design is the scientific method you will use to obtain the information you are seeking.
