Variables represents the measurable traits that can change over the course of a scientific experiment. In all there are six basic variable types : dependent, independent, intervening, moderator, controlled and extraneous variables.
What are the 3 types of variables in research?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled .

What are the 5 types of variables in research?
There are different types of variables and having their influence differently in a study viz. Independent & dependent variables, Active and attribute variables, Continuous, discrete and categorical variable, Extraneous variables and Demographic variables .
How many variables should a research topic have?
You should have at least four independent variables .
What are the two major types of variables in research?
The independent variable is the antecedent while the dependent variable is the consequent. If the independent variable is an active variable then we manipulate the values of the variable to study its affect on another variable.
What are the 2 types of variables in research?
- Discrete variables represent counts (e.g. the number of objects in a collection).
- Continuous variables represent measurable amounts (e.g. water volume or weight).
What are the major types of variables?
- DEPENDENT VARIABLES.
- INDEPENDENT VARIABLES.
- INTERVENING VARIABLES.
- MODERATOR VARIABLES.
- CONTROL VARIABLES.
- EXTRANEOUS VARIABLES.
What are the 4 types of variables used in research?
You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio ). These refer to the levels of measure associated with the variables.
Why are variables important in a research study?
In conclusion, variables are important because they help to measure concepts in a study . Because quantitative studies focus on measuring and explaining variables, choosing the right variables is important. The first step is to identify the correct variables to measure a property.
What are key variables in a research study?
The key variables are the major terms to use when searching for research articles for the Literature Review . The key variables are the terms to be operationally defined if an Operational Definition of Terms section is necessary. The key variables provide focus to the Methods section.

What are the two types of data?
We’ll talk about data in lots of places in the Knowledge Base, but here I just want to make a fundamental distinction between two types of data: qualitative and quantitative . The way we typically define them, we call data ‘quantitative’ if it is in numerical form and ‘qualitative’ if it is not.
What type of variable is age?
There are 2 types of numerical variables: ● Continuous variable : A numerical variable that can take values on a continuous scale (e.g. age, weight).
How do you identify a variable?
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 .
