What are the types of experimental research?
The types of experimental research design are determined by the way the researcher assigns subjects to different conditions and groups. They are of 3 types, namely; pre-experimental, quasi-experimental, and true experimental research .
What are the 3 characteristics of experimental research?
Several kinds of experimental designs exist. In general, designs that are true experiments contain three key features: independent and dependent variables, pretesting and posttesting, and experimental and control groups . In a true experiment, the effect of an intervention is tested by comparing two groups.
What is an example of experimental psychology?
For example, researchers could perform a study to look at whether sleep deprivation impairs performance on a driving test . The experimenter could control for other variables that might influence the outcome, but then vary the amount of sleep that participants get the night before a driving test.
