Question

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.

Answer 1

Research can be classified into different types.the basic types are

1.descriptive vs analytical

2.applied vs fundamental

3.qualitative vs quantitative

4.conceptual vs empirical

In these types quantitative is assessed based on the assessment of quantity

In Qualitative the quality or kind is assessed

Experimental and quasi experimental come under the classification of quantitative method.

*experimental-it uses a support of scientific method to establish cause effect relationship among a group of variables.

E.g..a study of the effect of a diet plan on blood pressure.

*quasi experimental-it tries to establish a cause effect relationship between two or more variables.

E.g..a study on the effect of the introduction of a health education programme in a school on childhood obesity.

*non experimental- when a study can't be controlled or manipulated by the researchers it can be called as non experimental research. It relies on interpretation or observations to reach a result.

*differences-methodology is entirely different .in experimental experiments are allowed whereas in non experimental the researchers can only observe or interpret

-in experimental research has the ability to seek cause effect relationship while non experimental cannot give a certainty on result.

*we could make our research effectively by

-Narrow the topic-focus on a specific topic rather many

-Set preliminary goals-set priority objectives

-assess the scope- search for the trends and scope of the subject

-possible sources- find out relevant resources and materials to support study

-avoid plagiarism-to get an identity and freedom
