Consider the following example research question: What is the relationship between Emotional Intelligence and conventional Academic Peiformance? , the treatment), as opposed to extraneous or unaccounted-for variables. Specifically, internal validity has to do with causal inferences-hence, the reason why it does not apply to nonexperimental research. The goal of nonexperimental research is to describe phenomena or to explain or predict the relationship between variables, not to infer causation (although there are circumstances when cause and effect can be inferred from nonexperimental research, and this is discussed later in this book).
