Jun 27, 2021 · The goal of experimental research design is to provide more definitive conclusions about the causal relationships among the variables in the research hypothesis than is available from correlational designs. If the null hypothesis is rejected, it means that alternative hypotheses (research hypothesis) are accepted, and if the null hypothesis is accepted, the alternate hypothesis is rejected automatically. We begin with a general definition of, non-experimental research, along with a discussion of when and why non-experimental research is more appropriate than experimental research. So, for example, you experience gravity by intentionally dropping a stone from several heights. 1 A Model of Scientific Research in Psychology 2.
