For this task you will prepare a tutorial on quasiexperiment

For this task, you will prepare a tutorial on quasiexperimental and experimental designs. Your tutorial will serve as a step by step guide as to how you would use statistical analysis in both designs.

Solution

Experiments and Quasi-Experiments

An experiment is a study in which the researcher manipulates the level of some independent variable and then measures the outcome. Experiments are powerful techniques for evaluating cause-and-effect relationships. Many researchers consider experiments the \"gold standard\" against which all other research designs should be judged. Experiments are conducted both in the laboratory and in real life situations.

Types of Experimental Design

There are two basic types of research design:

The purpose of both is to examine the cause of certain phenomena.

True experiments, in which all the important factors that might affect the phenomena of interest are completely controlled, are the preferred design. Often, however, it is not possible or practical to control all the key factors, so it becomes necessary to implement a quasi-experimental research design.
