What is the difference between a correlation, a true experimental design, a quasi-experimental design and single case research?

Expert Solution

A true experimental design will have the following elements:

Random assigning the sample groups
There must be a viable control group
An independent variable that can be varied and a dependent variable that has to be measured.
Random assigning to either the control or experimental groups of tested subjects

A Quasi-experimental design includes the feature of a true experiment but a random sample. Is generally missing in this design and this leads to a difficulty in demonstrating the cause and effect relationship in the research.

A correlational study determines how two variables are correlated i.e. positively, negatively or there is no relationship. It does not find a cause and effect relationship.

Single case design (SCD), is used to rigorously test the success of an intervention or treatment on a particular case i.e., a person, school, community-based on an evaluation method that provides evidence about the general effectiveness of an intervention

give an Explanation of the following comparison through some examples: Quasi-experimental and true experimental research designs both attempt to determine causal relationships by applying a treatment or condition to one group and comparing the outcome with a control group. A true experimental design is the gold standard in assessing causal relationship because it requires that subjects be randomly assigned to the groups to avoid bias and it controls all extraneous variables
