Types Of Variables: When It Comes To Research, Let’s Find Out.

It is essential to have a solid understanding of the role that variables play in research because they describe the characteristics of the things being investigated. You might want to consider some variables, such as the characteristics of the people who will participate in your research study, the tools you will use, or even the environment in which your experiment will be carried out. 

Suppose you are a researcher and you do not understand the various types of variables that contribute to the results of your study. In that case, you risk making erroneous assumptions about those results and going down the wrong path when trying to draw conclusions based on those results.

The characteristics of your research participants, the tools you use to carry out your research, and the environments in which you carry out your research are all examples of categories that can be used to classify variables in research. To put a hypothesis to the test, a research study will use three distinct kinds of variables: independent, dependent, and controlled variables.

To determine how one variable (independent or manipulated) affects another variable (dependent or response), which allows you to measure the effect of the variable in question, the variable in question must first be subjected to some form of manipulation. One way to think about it is as a process that brings about some kind of change for a particular reason (like how psychotherapy can alter a person’s behaviour).

Three different types of variables used in the research.

There are three different categories for the different kinds of variables that are used in research. When dealing with data containing an independent variable, the researcher can alter the variable’s value. This is something that you will not always be able to do, but it is observed in most studies. 

During an experiment, it is possible to measure a dependent variable that shifts in tandem with the independent variable due to the manipulation of the independent variable. This is made possible as a consequence of the independent variable. 

In most experiments, at least one variable is controlled, meaning that its value will remain constant throughout the experiment. To better understand how a change in one thing affects another, it is still essential to be familiar with how a change in one thing can affect other things, such as a change in the body’s temperature.

Consider for a moment that you are interested in learning whether or not you are susceptible to experiencing heartburn due to eating foods that are high in spice. I asked ten people if they experienced heartburn regularly, and then I gave each of them a different spicy hot sauce to consume with their dinner for five nights in a row, beginning with the least intense level. 

This allowed me to determine whether or not they had heartburn regularly. After that, I will inquire as to whether or not they experience heartburn in the evening after eating dinner; this will enable me to determine whether or not my hypothesis is accurate.

Dependent variable.

Variants are sorted into three primary categories based on the type of the variable being considered. The researcher must understand that an independent variable is something that the researcher can alter to achieve the desired results. On the other hand, there is a catch to this, and that is the fact that it is not always feasible to accomplish this objective. 

During an experiment, a dependent variable is measured. For the experiment, this dependent variable changes due to the experimenter manipulating an independent variable, resulting in changes to the dependent variable. 

There are two variables: one that is controlled and another that remains constant throughout the experiment. A controlled variable is altered throughout the entirety of an experiment or study, whereas a constant variable remains unchanged throughout the process. If you do not include this variable as one of the factors being investigated in your study or experiment, you should not expect it to yield accurate results.

Independent variables.

A dependent variable can only be affected by the researcher’s results of the experiment. Because of this, the effect of this variable on the dependent variable needs to be tested at various levels before you can determine how it affects the variable in general. 

If, for instance, you wanted to investigate how high oxygen levels in hypoxic conditions affect a person’s ability to remain awake, then oxygen content would be the independent variable, and sleepiness would be the dependent variable. This is because you are trying to pinpoint oxygen levels’ effect on people’s ability to remain awake. For example, if you wanted to investigate how high oxygen levels in hypoxic conditions affect a person’s ability to remain awake, oxygen content would be the independent variable.

Controlled Variable 

During the experiment, one variable, known as the controlled variable, will be maintained in its original state. This will allow you to determine whether or not changes made to the independent variable will have an impact on the dependent variable. Take, for instance, the scenario in which we wanted to determine whether people can stay awake in hypoxic environments by determining the amount of oxygen that is carried in their bodies. 

Because of this, it was impossible to let the temperature fluctuate because any temperature change would have affected both the independent variable (oxygen) and the dependent variable (sleepiness).


In conclusion, there are three distinct types of variables: independent, dependent, and controlled. To properly manipulate the dependent variable, it is also necessary to manipulate the independent variable to some degree. 

One type of variable is known as a “dependent variable,” which shifts in response to changes in the values of other variables or factors. During an experiment, a controlled variable does not undergo any changes; instead, it stays the same (for example, the temperature) from the beginning to the end of the study. This is another crucial point to keep in mind.
