Detailed Solution
Download Solution PDFThe correct answer is Causality. The internal validity factor in research is related to the issue of causality.
Important Points
Internal validity is the extent to which you can be confident that a cause-and-effect relationship established in a study cannot be explained by other factors.
- Internal validity makes the conclusions of a causal relationship credible and trustworthy.
- Without high internal validity, an experiment cannot demonstrate a causal link between two variables.
To establish internal validity, a study must be designed in a way that minimizes alternative explanations for the observed relationship between variables. This involves controlling for extraneous variables that might affect the results and ensuring that the study is conducted in a rigorous and unbiased manner.
Therefore, the correct answer is Causality.
Additional Information
How to check whether your study has internal validity
There are three necessary conditions for internal validity. All three conditions must occur to experimentally establish causality between an independent variable A (your treatment variable) and dependent variable B (your response variable).
- Your treatment and response variables change together.
- Your treatment precedes changes in your response variables
- No confounding or extraneous factors can explain the results of your study.
