Study Notes

Research Design

Researchers choose a design that is most appropriate to test the study hypothesis or answer the research question.
Research design can be quantitative or qualitative.
Experimental design can be true experimental, quasi-experimental, or pre-experimental.
Non-experimental design can be survey, correlational, comparative, or methodological.

Research Setting

The setting for a research study should be described and deemed appropriate for the study.

Population and Sample

Research population is identified and is the group of people or objects for whom the study findings are generalized.
A subgroup of the population is called a sample.
The sample (subjects) are identified and described.
Methods taken to protect subjects' rights are discussed in detail.
Permission obtained to conduct the study is mentioned.
Assignment of the sample to a group (if relevant) is mentioned.
Consent procedure is described.

Instruments or Tools

Data collection tools are clearly described.
Scoring procedure and range of possible scores on the tool are included.
Tools are tested for validity and reliability.
Copies of tools should be included in the appendix, each tool in a separate one.

Data Collection Methods

Data collection should be detailed and explicit to allow exact replication of a research study.
Any changes or difficulties confronted should be explained to help bring the process of data collection alive.
Five general questions are asked in evaluating the data collection section: what, how, who, where, and when.

Data Analysis (Results)

Appropriate statistical tests were selected and clearly presented in text, tables, and figures.
Results are presented accurately and completely in tables, figures, and in text.
The probability value of statistical tests and degree of freedom are given.
Headings of tables and figures are clear.

Discussion of Findings

Findings or facts of the study are presented in a completely objective manner.
The author interprets the results, giving more subjective information than the finding section.
The study's findings are compared with those of other research studies in the literature review.
The author explains whether the findings supported or failed to support the study hypothesis and questions.
Clinical significance of the significant and nonsignificant results is discussed.
Study limitations and how they affect the study results are discussed.

Conclusion

Answers the 'so what' questions at the end of the study.
Demonstrates the meaning and worth of the research study.
Attempts to make generalizations based on the findings of the study.
