RESEARCH DESIGNS

The method you choose will affect your results and how you can conclude on the findings. Most scientists are interested in getting reliable observations which can help understand a phenomenon.

There are two main approaches to a research problem:

• Quantitative Research
• Qualitative Research

There are various designs which are used in research, all with specific advantages and disadvantages:

• True Experimental Design
• Quasi-Experimental Design
• Double-Blind Experiment
• Descriptive Research
• Literature Study/Archive Study
• Case Study
• Survey
• Twin Studies
• Meta-analysis
• Observational Study
• Cohort Study
• Longitudinal Study

What design you choose depends on different factors.

• What information do you want?
• How reliable should the information be?
• Is it ethical to conduct the study?
• The cost of the design
