. Internal vs external validity example In the driving reaction times study you are able to control the conditions of the experiment and ensure that there are no extraneous factors that could explain the outcome. External validity asks whether the findings of a study can be generalized to. Because the experiment has high internal validity you can confidently conclude that listening to the podcast causes slower reaction. On the other hand external validity is the degree up to which the research outcome applies to other situations.

When research is designed to investigate cause and effect relationships explanatory research through the direct manipulation of an independent variable and control of extraneous variables.

Internal validity we are making the experiment more and more artificial and thereby its generalizability external validity suffers. Internal validity is a level up to which causal relationships between variables are trustworthy. Lack of internal validity implies that the results of the study deviate from the truth and therefore we cannot draw any conclusions. The balance technique would allow for more generalizability than would the eliminate or hold constant techniques.
