describe some of the important research designs used in experimental hypothesis testing research study
Answers
The classic experimental design definition is, “The methods used to collect data in experimental studies.”
There are three primary types of experimental design:
Pre-experimental research design
True experimental research design
Quasi-experimental research design
The way you classify research subjects, based on conditions or groups, determines the type of design.
1. Pre-experimental research design: A group, or various groups, are kept under observation after implementing factors of cause and effect. You’ll conduct this research to understand whether further investigation is necessary for these particular groups.
You can break down pre-experimental research further in three types:
One-shot Case Study Research Design
One-group Pretest-posttest Research Design
Static-group Comparison
2. True experimental research design: True experimental research relies on statistical analysis to prove or disprove a hypothesis, making it the most accurate form of research. Of the types of experimental design, only true design can establish a cause-effect relationship within a group. In a true experiment, three factors need to be satisfied:
There is a Control Group, which won’t be subject to changes, and an Experimental Group, which will experience the changed variables.
A variable which can be manipulated by the researcher
Random distribution
This experimental research method commonly occurs in the physical sciences.
3. Quasi-experimental research design: The word “Quasi” indicates similarity. A quasi-experimental design is similar to experimental, but it is not the same. The difference between the two is the assignment of a control group. In this research, an independent variable is manipulated, but the participants of a group are not randomly assigned. Quasi-research is used in field settings where random assignment is either irrelevant or not required.
