Describe a research topic you might study using an experimental, quasi-experimental, or correlational design. Why is the design appropriate to this specific topic?
A research topic i might study using quasi experimental design is in the study of big data.
Big data has massive sample size and high dimensionality which brings heterogeneity, noise accumulation, spurious correlation and incidental endogeneity. These features of big data calls for new statistical methods that can handle these challenges.
Penalised quasi likelihood method of quasi experimental design can be used to handle noise accumulation issue.

1).Which type of research design (experimental or quasi-experimental) do you think is more likely to have higher validity? Why? 2).What type of methodology would you use to evaluate the effectiveness of a family preservation/child welfare intervention aimed at reducing the risk for future neglect or abuse in families referred for abuse or neglect?
Be able to describe an experimental study, correlational study, and naturalistic study? What is the goal of each? What is a hypothesis versus a theory?
Provide an example of experimental, quasi-experimental, and non experimental research from the GCU Library and explain how each research type differs from the others. When replying to peers, evaluate the effectiveness of the research design of the study for two of the examples provided.
Which study approach (example, cross-sectional survey, retrospective, correlational, experimental, etc) would be the best to the test the question below.State why the study design you selected is appropriate and address any limitations associated with the approach. Question Is Alcohol use related to the risk of poor academic performance among college students living in the United State?
Assign the correct research method to the example: Survey Naturalistic Observation Case Study Correlational Design Experimental Research Design Three individuals who have been diagnosed with a rare disorder are studied in detail, and the researcher makes comparisons between them to better understand the disorder A researcher watches and records the social behavior of individuals during a major holiday sale at the mall A sample of individuals is divided into two groups, one of which receives an antidepressant that is being...
A research study is conducted where 15 participants complete a 12-week control period followed by a 12-week exercise intervention. What type of research is this? True experimental Correlational Pre-experimental Quasi-experimental Question 2 (1 point) ✓ Saved What type of research collects fairly unstructured data via interviews and focus groups? Quantitative Qualitative Which type of research is attempting to establish the presence/absence of "cause- effect"? Correlational Descriptive Experimental Historical Question 4 (1 point) ✓ Saved When considering the threats to internal...
Correlational versus Experimental Studies 1. a. describe a correlation b. describe an experiment C. describe the difference between correlations and experiments For each of the following studies: 2. Decide whether the study is correlational or experimental. 3. Describe why you made your choice between an experiment or correlation. Do not simply restate the definition of an experiment or correlation. For each study below, do "a" or "b", but not both. a. If the study is correlational, identify the two variables...
A quasi-experimental or nonexperimental research design that compares different groups of participants is called a(n) one that compares the same group of participants is called a(n) whereas a. pre-post design; nonequivalent groups design. b. nonequivalent groups design; pre-post design. c. within-subjects experimental design between-subjects experimental design. d. between-subjects experimental design, within-subjects experimental design
what is the difference between experimental research and correlational research and which research type do you think would have more accurate results or is better?
When looking at psychological research, it is generally thought that experimental research methods provide the best tool for conducting research. However, some research illustrates that correlational studies and other descriptive methods provide an equally important opportunity for conducting research. After completing this week's readings, discuss the benefits and disadvantages of using an experimental design. In your discussion, be sure to examine how the different research procedures might help to convey results to different audiences. For example, would observational data be...
