Internal vs. External Validity
- What is the difference between internal and external validity?
Internal validity and external validity are two critical concepts in research methodology that assess the credibility and applicability of research findings. Here’s a breakdown of their differences:
Internal Validity
- Definition:
- Internal validity refers to the degree to which a study accurately establishes a cause-and-effect relationship between the independent and dependent variables within the context of the study itself.
- Focus:
- Internal validity is concerned with the integrity of the study’s design, execution, and analysis. It assesses whether the results of the study can be attributed to the manipulation of the independent variable rather than other confounding factors.
- Threats to Internal Validity:
- Confounding Variables: Other variables that may influence the dependent variable and thus distort the results.
- Selection Bias: Differences in characteristics between groups being compared can lead to inaccurate conclusions…
