Validity is divided into two parts namely internal and external validity when the relationship in research is affected by the causes and effects of testing. In this article, we are going to differentiate between Internal and External Validity.

Internal validity examines whether the study design, conduct, and analysis answer the research questions without bias. External validity examines whether the study findings can be generalized to other contexts.
