Question

What sre the methods of quasi experimental research( psychology)?

Answer 1

A quasi-experiment is designed a lot like a true experiment except that in the quasi-experimental design, the participants are not randomly assigned to experimental groups.

In a true experiment, research participants have an equal chance of being assigned to any condition of the independent variable (the one being manipulated by the researcher) that is involved in the study. So, for instance, if a researcher was examining the effects of caffeine on reading comprehension, she might randomly assign participants to one of three independent variable conditions: those who drink one cup of soda, two cups of soda, or no soda. She might then assess each person's reading comprehension abilities following exposure to the independent variable. In a true experiment, each participant who volunteered would have an equal chance of being assigned to any of the three groups.

Quasi-experiments are employed when the researcher is interested in independent variables that cannot be randomly assigned. Usually this happens when the independent variable in question is something that is an innate characteristic of the participants involved. Let's look at a couple of examples to help illustrate the point.
