Study Notes
Correlational Research
- Commonly used in quantitative research within social sciences like psychology, political science, and economics.
- Seeks to identify patterns and associations in human behavior.
- Example: Examining the relationship between hours spent on social media and academic performance in students.
- In economics, it assesses the influence of economic variables, such as the relationship between foreign exchange rates and a country's credit rating.
- Political science applications include studying the correlation between crime rates and election results of politicians.
Nature of Correlation
- Correlation is a statistical measure indicating the relationship between two variables, defining whether they are associated, the strength of that association, and the direction (positive or negative) of the relationship.
- Examples of correlations include sleep hours versus test scores in students.
- Possible outcomes:
- No significant relationship exists.
- Higher test scores correlate with increased sleep hours.
Distinction from Causation
- Correlational research can confirm if a relationship exists between variables but does not establish causation between them.
Causal Research
- Focused on understanding cause-and-effect relationships.
- Example: Investigating how an additional unit of a food ingredient affects the decay rate of a food sample, demonstrating a clear cause (ingredient) and effect (decay).
- Commonly applied in natural sciences such as biology, chemistry, and physics, though not limited to these fields.
Applications in Chemistry
- Causal research involves conducting experiments to evaluate how changes in one substance impact another’s characteristics, establishing causal links between variables.
Research Method Types
- Survey research is considered a correlational type of quantitative research.
- Experimental research is positioned to explore causation rather than mere correlation.
