Can Create Artificial Situations By having such deep control over the variables being tested, it is very possible that the data can be skewed or corrupted to fit whatever outcome the researcher needs. This is especially true if it is being done for a business or market study. This can cause the testing to take a very long amount of time and use a large amount of resources and finances. These costs could transfer onto the company, which could inflate costs for consumers.

Home 7 Advantages and Disadvantages of Experimental Research. The Advantages of Experimental Research 1. The Disadvantages of Experimental Research 1. Every single new medicine or drug is testing using this research design. This is largely due to fact that all other variables are tightly controlled which may not create a fully realistic situation.
Because the situations are very controlled and do not often represent real life, the reactions of the test subjects may not be true indicators of their behaviors in a non-experimental environment.
Human error also plays a key role in the validity of the project as discussed in previous modules. It may not be really possible to control all extraneous variables. The health, mood, and life experiences of the test subjects may influence their reactions and those variables may not even be known to the researcher.
The research must adhere to ethical standards in order to be valid. These will be discussed in the next module of this series. Experimental research designs help to ensure internal validity but sometimes at the expense of external validity. When this happens, the results may not be generalizable to the larger population. If an experimental study is conducted in its natural environment, such as a hospital or community, it may not be possible to control the extraneous variables.

It gives researchers a high level of control. When people conduct experimental research, they can manipulate the variables so they can create a setting that lets them observe the phenomena they want.
They can remove or control other factors that may affect the overall results, which means they can narrow their focus and concentrate solely on two or three variables. In the pharmaceutical industry, for example, scientists conduct studies in which they give a new kind drug to a group of subjects and a placebo drug to another group.
At the end of the study, the researchers analyze the results to see how the new drug affects the subjects and identify its side effects and adverse results. It allows researchers to utilize many variations. As mentioned above, researchers have almost full control when they conduct experimental research studies. This lets them manipulate variables and use as many or as few variations as they want to create an environment where they can test their hypotheses — without destroying the validity of the research design.
In the example above, the researchers can opt to add a third group of subjects in addition to the new drug group and the placebo group , who would be given a well-known and widely available drug that has been used by many people for years. This way, they can compare how the new drug performs compared to the placebo drug as well as the widely used drug.
The investigator has the ability to tailor make the experiment for their own unique situation, while still remaining in the validity of the experimental research design. The Disadvantages of Experimental Research. 1. Largely Subject To Human Errors Just like anything, errors can occur. This is especially true when it comes to research and .
Experimental research focuses mainly on the relationships between known variables. This research also provides strong casual interpretational evidence. The advantages and disadvantages of Experimental research are presented below.
Benefits and Limitations Of Experimental Research. The following module will discuss the benefits and limitations associated with experimental research. Learning Objectives: List and explain the advantages and benefits of experimental research. List and explain the disadvantages and limitations of experimental research. The advantages and disadvantages of experimental research show that it is a useful system to use, but it must be tightly controlled in order to be beneficial. It produces results that can be replicated, but it can also be easily influenced by internal or external influences that may alter the outcomes being achieved.
