Week 4 discussion | PSY 326 Research Methods | Ashford University

In contrast to qualitative designs, which are all basically non-experimental and descriptive, quantitative research designs may be either experimental or non-experimental. Within the non-experimental category, descriptive and correlational research are sub-categories.

Using the Ashford University Library databases, look for a scholarly/peer-reviewed quantitative research study on the topic you selected in Week 1. In your initial post,

  • 1. Appraise the differences between experimental and non-experimental research.
  • 2. Differentiate between a correlational study and an experimental study.
  • 3. State the hypothesis being tested in the selected quantitative research study.
  • 4. Identify the major variables and categorize them as independent or dependent.
  • 5. Describe the methods and results of the study.
  • 6. Determine whether the study is descriptive, correlational, or experimental, and explain why it fits this classification.
