Let's look at three to consider.
1. How would you use the different types of research designs? What are some strengths and weaknesses of each?
There are various designs which are used in research, all with specific advantages and disadvantages:
- True Experimental Design
- Quasi-Experimental Design
- Descriptive Research (http://www.experiment-resources.com/research-designs.html#ixzz0oWeFHeLD)
1. True Experimental Design
This design is an integral part of science, usually acting as a final test of a hypothesis. This is when it used to test hypothesis. Whilst they can be a little artificial and restrictive, they are the only type of research that is accepted by all disciplines as statistically provable as they offer control.

- The results of a true experimental design can be statistically analyzed and so there can be little argument about the results.
- It is also much easier for other researchers to replicate the experiment and validate the results.
- For physical sciences working with mainly numerical data, it is much easier to manipulate one variable, so true experimental design usually gives a yes or no answer. (http://www.experiment-resources.com/true-experimental-design.html#ixzz0oWfhyavP)
- Whilst perfect in principle, there are a number of problems with this type of design. Firstly, they can be almost too perfect, with the conditions being under complete control and not being representative of real world conditions.
- For psychologists and behavioral biologists, for example, there can never be any guarantee that a human or living organism ...
This solution discusses the different types of research designs (these include true experimental designs, quasi-experimental design and descriptive research. Strengths and weaknesses are discussed.
