What are two ways that confounds can be controlled in a quasi-experimental design, and be able to identify examples
Two ways that confounds can be controlled in a quasi-experimental study is by the addition of control groups and use of counter balancing techniques.

A researcher used a two-group quasi-experimental (nonequivalent control group) design to test the effect of a Tai Chi intervention on quality of life in nursing home residents. The elders’ age was statistically controlled. What procedure for statistical control might the researcher have used? A. Propensity score matching B. Analysis of covariance C. Manipulation checks D. Power analysis
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.
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 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
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?
What are the major differences between quasi-experimental and experimental quantitative research?
Question 382 pts Which of these would be the stronger quasi-experimental design? Group of answer choices one-group posttest-only design posttest-only design with a nonequivalent control group pretest-posttest design with a nonequivalent control group one-group pretest-posttest design
EXHIBIT 2 Fuzzy Quasi Is a Bear Quasi experiments are studies that are unable to use randomization to evaluate effectiveness of interventions. This can make it difficult to tease out possible confounders and assess the integrity of any cause and effect claims. Consider this example adapted from a paper in Clinical Infectious Diseoses A hospital wants to know if providing alcohol- based hand cleaners for staff will reduce the rate at which bacterial infections occur in the patient population. The...

Which of the following are valid reasons for doing a factorial experimental design? (select the 3 correct answers) A. It's easier to establish control and eliminate confounds B. You can test multiple variables simultaneously C. The complexity of the situation would be more like what's found in the real world D. It allows you to see interactions between variables
