When designing research, you must take into account the different methods and experimental research types that are available.
There are two main types of research: non-experimental and experimental. It’s critical to understand the advantages and disadvantages of each type in order to choose which is best for your research goals.
Experimental research is a type of quantitative research that controls the variables in order to test a hypothesis. Non-experimental research does not control the variables but instead looks at naturally occurring factors without manipulating them to test a hypothesis.
This article explains more about the benefits and drawbacks of experimental versus non-experimental research so you can decide which one is right for your project.
What is Experimental Research?
Experimental research is a scientific method where the researcher manipulates the variables in the experiment to see how this influences the findings. In experimental research, the research subject(s) are subjected to one or more manipulations of their control variables while the effects of these manipulations are being monitored. Because it enables the adjustment of control variables, it is well known.
The goal of the experiment is to test a hypothesis. The data collected during the experiment will help you understand how accurate your hypothesis is.
Experiments are a type of quantitative research that aims to control all the variables in order to accurately test a hypothesis. Experiments are typically used in social sciences such as psychology, economics, or sociology. Other fields like biology also use experimental research, but they often use a different method called “controlled laboratory experiments”.
Experiments are also used in business research, but businesses often employ a different type of experimental research called “field experiments”.
What is Non-Experimental Research?
Non-experimental research does not experimentally manipulate the variables directly. Instead, it looks at naturally occurring factors without experimenting with them. Research that is non-experimental does not manipulate a control variable or an independent variable. In non-experimental research, variables are measured as they are without any additional manipulation.
These types of research are usually quantitative because they don’t manipulate the variables, but they don’t employ the same experimental approach as an experiment. To conduct non-experimental research, you must first define the population that you want to study. Then, you would take sample data from that population to find out what the results are.
The goal of non-experimental research is to find out what naturally occurs in the environment without directly manipulating anything. This means that the researcher does not change any variables during the research process. Non-experimental research is often used in fields like social sciences or economics where it is hard to experimentally manipulate the variables.
Benefits of Experimental Research
Experimental research has several advantages.
- First, it allows you to control many different factors to test the accuracy of your hypothesis. This means that you can completely control the outcome of your research if you use the right methods.
- Experimental research also allows you to conduct the research in a short amount of time, meaning you can get accurate results quickly. This is important for businesses that need to make quick decisions about products or services.
- Experimental research often leads to the creation of new products or solutions because researchers can test multiple solutions at the same time. Many businesses use experimental research to create new products or services because it allows them to test different variables that would otherwise be difficult to control in a non-experimental research setting.
Disadvantages of Experimental Research
Experimental research does come with a few disadvantages.
- First, it can be very expensive to conduct and may require specialized equipment or employees. You also need to hire professionals to create a hypothesis and conduct the experiment.
- Experimental research can also be time consuming. You must create the right conditions to ensure that the right variables are being tested. This can take a long time.
- Experimental research can also be difficult to control. If you don’t have the right conditions, you may not get accurate results. Researchers also have to make sure that other factors don’t influence the outcome of the experiment.
- Experimental research can also lead to inaccurate findings if the researcher makes a mistake or if the conditions are not right for the experiment.

Benefits of Non-Experimental Research
- Non-experimental research does not have the same financial or time requirements as experimental research. You can conduct non-experimental research with minimal resources and you don’t need to create a hypothesis in order to conduct it. This means that you don’t have to hire specialists or spend as much money as you would on an experiment.
- Non-experimental research is also easier to control than an experiment because you don’t have to create a controlled setting. Instead, you simply observe what naturally occurs in the environment. This means that you don’t have to worry about outside factors influencing the outcome of the research.
- Non-experimental research is also less risky than an experiment because you don’t have to worry about making a mistake. If something goes wrong during the research, you don’t have to start the experiment over again. Instead, you can simply make a note of it and continue with the research.
Disadvantages of Non-Experimental Research
Non-experimental research does have a few disadvantages.
- First, it does not allow you to test your hypothesis as accurately as experimental research does. This means that you don’t really know if your product or idea will work in the real world.
- Non-experimental research is also limited by the number of variables that are naturally occurring in the environment. This means that you might not be able to find the right data or factors to test your hypothesis.
- If you want to test a lot of different variables at once, non-experimental research can become difficult to conduct. You must then separate the data in order to find out which factor is influencing your findings.
Difference Between Experimental and Non-Experimental Research
The primary difference between these two forms of research is how they approach manipulating control variables. Non-experimental research does not allow for the manipulation of control variables.
Example: Experimental vs Non-Experimental Research
Laboratory experiments in which various chemical elements are mixed together to observe how one element affects another are instances of experimental research, whereas studies into the properties of various chemical elements are examples of non-experimental research.
Which Type of Research is Right for You?
When choosing between experimental and non-experimental research, you should remember that both methods have their benefits and drawbacks. No one research method is better than the other. Instead, different research types are better for different projects.
You should choose experimental research if you want to test a hypothesis as accurately as possible. This type of research is good for testing new products or services because you can control the variables directly.
You should choose non-experimental research if you want to observe naturally occurring factors. This type of research is good for projects where you can’t experimentally manipulate the variables or where it’s difficult to do so.
