Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity, consider the importance of each of these aspects in judging the validity of quantitative research.Discussion: Validity in Quantitative Research DesignsValidity in research refers to the extent researchers can be confident that the cause and effect they identify in their research are in fact causal relationships. If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value. Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity. In this Discussion, you consider the importance of each of these aspects in judging the validity of quantitative research.To prepare:Review the information in Chapter 10 of the course text on rigor and validity.Read the method section of one of the following quasi-experimental studies (also located in this week’s Learning Resources). Identify at least one potential concern that could be raised about the study’s internal validity.Metheny, N. A., Davis-Jackson, J.,
