PRLog - March 26, 2014 - CHENNAI, India -- Experimental study is usually prevalent in disciplines like: sociology, psychology, physics, chemistry, biology, etc. In these disciplines research study is conducted through manipulation and controlling test to have understanding over the particular casual processes. In these types of studies, variables undergo manipulation to ascertain the effect on a dependent variable. Researcher involved in the study manipulates the variables (one or more than one) to his or her advantage and controls over change in other variables while measuring. Therefore, in experimental study, something in research is influenced to observe the consequences. Research methodology for experimental study features in steps like:
Designing of the study
Sharing the findings
The use of experimental study for PhD thesis is done, when there is need of: time priority in casual relationship, consistency in casual relationship, magnitude of correlation. The prime reason of experimental study is to predict the phenomenon to explain the kind of causation. After identifying the research problem, experiment is designed to get the answer. So, it is different from other types of research, where the usual process of research methodology is followed. In this respect of experimental study, there is a need for conducting the experiments carefully to ensure accurate result. It requires sampling groups to study. The reason for choosing the group is when it requires more than one condition. Hence, one sample group is at the disposal to serve as control group while the others are to serve for experimental conditions. Some of the sampling techniques used as per the research specific need are: probability, non-probability, simple random, stratified, systematic, cluster, sequential, etc.
There are some design features in experimental study and it depends on factors like: time, cost, ethics, measurement problems, and what is going to be studied and tested. Prominent designs are as:
Randomized controlled trials
Solomon four-group design
Between subjects design
Within subject design
Counterbalanced measures design
Matched subjects design
Since so many designs at your disposal to apply for the experimental study, you have to pick the right one to feature in the PhD dissertation. Hence, there is a need of one or two pilot study to pick the right experimental design in favor of your research. Therefore, concern and confusion might arise in selecting the research design. To assist you in conducting the experimental study, our experts will suggest picking the right one for yielding accurate result. Moreover, you might have problem in manipulating variables, identifying and controlling non-experimental factors, when to influence, etc. In these areas of concerns, the expertise of our experts will come handy to carry on the research with ease.
When it comes to writing of research methodology for experimental study, it needs to be presented comprehensively. This section is what draws the attention of evaluator to assess the basis of research and the plots to conduct it and obtain inference. Developing the content in this regard is, if left to the experts like we have for those having issues is the best option. We are ensuring solid write-up for your PhD thesis or dissertation (http://www.phdassistance.com/
