Examples of Experimental Research The goal of experimental research is to answer a research question. To answer this question using a fundamental research design, researchers randomly assign participants to at least two different groups: an experimental and a control group. Participants are tested before...
An experimental research design is a set of protocols that are designed to be used in a research experiment to test a hypothetical...

An example of the importance of experimental design and statistical analysis in dental researchIn this paper a specific dental investigation was used to demonstrate the value of several statistical principles. It was concluded that: Blind evaluation of tissues is important in preventing bias in ...
(no matter what anyone tells you!). If the situation is right, an experiment can be a very strong design to use. But it isn’t automatically so. My own personal guess is that randomized experiments are probably appropriate in no more than 10% of the social research studies that attempt ...
The meaning of EXPERIMENTAL DESIGN is a method of research in the social sciences (such as sociology or psychology) in which a controlled experimental factor is subjected to special treatment for purposes of comparison with a factor kept constant.

You should begin with a specificresearch question. We will work with two research question examples, one from health sciences and one from ecology: Example question 1: Phone use and sleep You want to know how phone use before bedtime affects sleep patterns. Specifically, you ask how the number...
Therefore, research on coal mass permeability associated with coal damage is critical to the investigation on gas outburst hazard and gas extraction in underground coal mines (Jiang et al., 2010; Palmer and Mansoori, 1996). Coal permeability undergoes dynamic changes during gas drainage from coal ...
