Components, Process, Strengths’, and Weaknesses of Correlation Research
Psychological and educational research can be separated into three categories,
- Historical research
- Qualitative research
- Quantitative research.
Number 3, Quantitative research, can also be separated into three categories,
- Descriptive research
- Experimental research
- Correlational research
Correlational research decides how variables are related. The data is identified then their relationships are investigated. Data is put together from various variables and statistical correlation methods are applied to the data. Correlation does not mean cause and affect like experimental research. At the most, the researcher will only be able to make small fundamental inferences.
Correlational Research examines the nature of the correlation or what one variable has to do with the other which can be either positive or negative. Predictions are then made that can be tested on samples. For example:
Hypothesis - Does drinking wine make you look sexy?
Test the Hypothesis using correlational research. You can either do a survey or conduct an experiment. The strengths of a survey are that they are easier to give, you can survey many people, variables etc. and you can be assured that it is not a real situation. Weaknesses of a survey would be that some questions you ask may prejudice responses, participants may not tell the truth when answering questions and even the survey may be biased.
