The Significance of Control Variables

A control variable is a thing that signifies continual or restricted in a research study. This variable is used for the objective of the study as well as the experiment also handles it. That is why control variables may affect the inquiry and its result. This is the perfect definition of a control variable. There are different kinds of variables in an investigation along with a control variable or controlled variable. Variables are nothing but just the values that can be changed with time. There are two changing variables available in a perfect investigation: independent variable and dependent variable. Control variables are very important when you are experimenting. It has to be kept constant. 

What Are The Reasons For The Importance Of Control Variables? 

Control variables help to improve the inner rationality of an inquiry by prohibiting the consequence of perplexing and other peripheral variables. This will enable you to make a causal or correlational connection between the variables of your choice. 

Besides the independent and dependent variables, all other variables that may affect the outcomes must be managed. If you are unable to handle the variables one will not build that they did not influence your results. The uncontrolled variables are alternative clarifications for your goods. 

Experiments And Control Variables:

At the time of investigation, a researcher wants to know the impact of an independent variable. But unfortunately, it only relies on the dependent variable. Control variables will give you the outcomes that are solely inflicted by your investigation. 

Control Variables And Non-Experimental Research 

In non-experimental research, you will not be able to regulate the independent variable. It occurs because of moral and logical reflections. In this place control variables are restricted. 

What Are The Differences Between Control Variables And Control Groups? 

A control group is not like the control variable. You can measure control variables by using a constant parameter. You may avail throughout the study for experimental as well as control groups. 

 A control group may not go through the experimental treatment concern and the outcomes of it are distinguished from those available in the experimental group. There is no treatment in a control group. 

Besides the research treatment, everything in an experimental method must be the same between the control and experimental groups. 

How To Control A Variable? 

The variables in experimental design can be controlled in numerous ways. Some of them are: 

Random Assignment Producers 

At the time of experimental studies with different groups, associates must be assigned at random to different situations. Random assignment will enable you to balance the features of groups. Furthermore, it will enable you to maintain the balance and assure no systematic disparities between them. 

Statistical Controls 

You may measure and manage for additional or excess variables statistically for removing their impacts on their variables. 

Standardized Procedures 

It is very important to utilize similar methods across all groups at the time of conducting the same investigation. The groups may differ only when the independent variable is manipulated. 


If you are going to experiment by using control variables and independent variables you have to check whether you have in-depth knowledge about the above-mentioned factors and definitions. If you have good theoretical knowledge you will be able to conduct numerous experimental processes. If you have any doubts, you may consult with your science teacher before investigating and writing a science assignment.
