Control variables are the variables (i.e., factors, elements) that researchers seek to keep constant when conducting research. If used properly, control variables can help the researcher accurately test the value of an independent variable on a dependent variable.

Q. Which variable is affected by the experimental variable?
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
Q. What type of variable represents the results from experimental manipulation?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
Independent variables included in the first step are demographic variables such as age, gender, marital status, and education, and in the next steps are eco- nomic related variables including employment status and self-rated economic condition.
Q. What is control variables in research?
Q. What is term control variable?
In experimental and observational design and data analysis, the term control variable refers to variables that are not of primary interest (i.e., neither the exposure nor the outcome of interest) and thus constitute an extraneous or third factor whose influence is to be controlled or eliminated.
Q. How do you Operationalise a variable?
Select indicators for each of your variables.
- Identify the main concepts you are interested in studying. Based on your research interests and goals, define your topic and come up with an initial research question.
- Choose a variable to represent each of the concepts.
- Select indicators for each of your variables.
Q. What is an extraneous variable?
Extraneous variables are all variables, which are not the independent variable, but could affect the results of the experiment. The researcher wants to make sure that it is the manipulation of the independent variable that has an effect on the dependent variable.
Q. What are variables in research methodology?
A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.
