If you are a student in scientific research or a person who loves to research data for your school assignments or experiments. Then you may be aware of control variables and control groups while doing research or experiment. Students often get assignments from their teachers on a regular basis to help them learn everything in their coursework. Doing experiments is also a part of your education system or a part of your course if you are a science student. The science students are mostly aware of everything involved in the research as that’s the main thing in the whole coursework.
A variable is basically an element that is a part of the research or experiment. A variable held at a constant position while doing the experiment to judge or check the relationship between multiple variables. If the variable stays in a constant position, it means it’s in the not changing position, also known as a constant variable. During an experiment, the students might need to learn a lot of things and experience the difference in movements. With the help of constant variables, the students are able to test or measure the relationship properly working between the variables.
When students learn the methods of experimenting and researching in their education year, they can be the greatest researchers and scientists in their life. If you are also looking to learn everything about the control variable and the control group. Then this article will be a helpful guide for you as we have specifically researched and written this to help you. By reading this article, your concepts will be clear, and you will be able to understand your research coursework more easily. We will be discussing control variables and control groups in depth.
What is the control variable?
Even after completing their degrees, many students keep asking or researching the answer to their question, “what is control variable?”
Well, the simplest definition of the control variable is any factor you need to hold at a constant position during the experiment. It can be a factor or a component, which is used to hold at a still position where it defines the relationship of other components. A control variable is also known as a constant variable or controlled variable. It is because the researcher or scientist can control it by putting it in a constant position based on their experiment.
While you are a student and your education year is in process, many students get assignments or research tasks. Then the students might need to research and find the result to submit to the teacher. Submitting the assignments of research is a part of your coursework. Doing all assignments during the academic year will help you in getting good grades. Many of the students take help from experts such as Online Dissertation help to do the assignments. Thus, it is a great option to take the help of great researchers or scientists who help you do experiments.
One of the best control variable examples is if you have received an assignment. For example, your teacher assigns you to find out or study what effect the water will be going to make on seed germination. Then, in such an experiment, the control variable can be light, temperature, and the speed it takes for seed germination. In his experiment, you will also find a few of the variables you would not be able to control, like noise, vibration, and humidity.
What is the meaning of a control Group?
Whenever you do an experiment for your assignments, you will need to do the experiment multiple times. It is because every scientist or researcher must make sure everything is perfectly done. Additionally, the result is also the same every time you do it to confirm that the experiment went well with everything. Here comes the control group, a set of experimental samples kept different from the independent variable. Otherwise, the control group is the samples or subjects we keep separately and do not expose to the independent variable.
As a student, you can get assignments for experimenting or researching many different things. It can be based on your niche of education or your coursework. It depends on the teacher which experiment they are assigning to you, and you need to complete it. Research assignments play an important role in boosting your marks for completing the degree. Controlled experiments are different types of experiments. Usually, the controlled experiments have control groups.
For example, your teacher may assign you to experiment and find out if zinc even helps people recover from colds faster. So, for doing that experiment, you collect many people, then you divide all these people into two different groups. The first group will be the experimental people who will be going to take zinc and check whether it helps them to recover from cold faster or not. Then the other group will be your control group because this group of people will take a placebo. This group will not be going to take zinc, and they will take the independent variable. So, this is how you do an experiment with a control group.
Control Variable vs. Control Group:
The students are aware of experimenting on a regular basis because teachers are assigning a lot of tasks every day. The experiments are really very different from just doing the essay writing assignments. The experiments involve deep research, hard work, and passion for finding the result. Sometimes, experimenting and researching can be confusing for students because there are different ways to do so. The students sometimes need to do A/B testing for doing the experiments.
Doing the experiments isn’t as easy as changing one factor and recording the outcome. It may take a deep understanding and answering the questions like; how it happened, why it happened, and what makes it happen. Additionally, sometimes, the students might also need to find answers for If and else conditions. Such as, there could be something else that can happen, or what if specific action didn’t work whatsoever.
Control variables are basically a way to change and test during experiments. The control variable helps you to keep certain things in a constant position and test different situations. In this way, the scientists or experimenters are able to find out different factors by keeping the variables in control. They can easily compare and find the answers that help them complete the experiments.
Furthermore, If you are looking to find the difference between the control variable and the control group. Then keep reading on further because we are going to disclose the relation or difference between these two things. This article is a helpful guide for researchers or students who are looking to gain some knowledge.
What is the difference between a Control Variable and a Control Group?
It is a common fact that the control variable and control group are not similar things. These are two different factors of experimenting. The control variable is meant to be held at a constant position, or it is used to measure the idea of the experiment or end result for both experimental or control groups. But, as variables, these two are really very different factors from each other. One is for controlling, and the other one is for experimental groups. Before you start doing your experiments or research, you must first understand the difference between them.
Understanding the difference between the control variable and the control group is important for a scientist or researcher. The better you can get the knowledge and clear your concepts then, the easier it will be for you to do the experiments.
A control group is different from the control variable because it doesn’t experience the experimental treatment because of the experiment type or interest. Either the control group has a standard type of treatment or no treatment at all. In experimental research, the control groups are the most common for it. You can also use them in another type of research while doing your experiment.
However, on the other hand, the control variable increases the inner validity of the research. It is because the control variable limits the influence of extra and confounding variables. It also helps you to maintain or establish a causal relationship between different variables while doing an experiment. Moreover, the relation you will establish with other variables can be correlational, which will help you in researching further bias. While doing the experiment, if you are able to control the variables, then it will impact the relationship. You will be able to demonstrate, and the result of the experiment will influence you.
