Experimental research describes the process that a researcher undergoes of controlling certain variables and manipulating others to observe if the results of the experiment reflect that the manipulations directly caused the particular outcome. This type of research differs from a descriptive study, and another one of its important aspects is the use of random assignment.Continue Reading
When experimental research happens, there are certain steps that scientists take, the first one being an effort to control certain variables, which can be controlled, and then systematically manipulating other variables. The purpose of using control and manipulation on the variables of the experiment is to see if the variables that are being manipulated have an effect on the results, or data. This way, scientists can text hypothesis and analyze outcomes to make new inferences from the research.
This makes experimental research extremely important. Another important aspect of experimental research is the usage of randomization. This technique ensures that subjects of an experiment are always randomly assigned, or that the methodology is always random so as to ensure that there will be no bias or error in the experiment that would otherwise compromise the results of the research. An example of randomization would be when subjects are designated to receive an experimental drug and the other subjects are to have a placebo. Randomization would dictate that these subject groups are made out of a completely random selection, and this would make sure that there is no bias or error because the subjects are blinded to their group designation.Learn more about Chem Lab
