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.
What are PDF variables?
Create and edit text variables. A text variable is an item you insert in your document that varies according to the context . For example, the Last Page Number variable displays the page number of the last page of the document. If you add or remove pages, the variable is updated accordingly.

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.
What is research variable and its types?
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 is variable in research with example?
Some attribute variables are age, gender , blood group, color of eyes, etc. We might want to study the effect of age on weight. ... The variable gender, for example, has only two values (male and female). Variables that take on only a handful of discrete non quantitative values are categorical variables.
What are 3 types of variables?
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 types of variables in research?
- Independent variables. ...
- Dependent variables. ...
- Intervening variables. ...
- Moderating variables. ...
- Control variables. ...
- Extraneous variables. ...
- Quantitative variables. ...
- Qualitative variables.
Why do we use variables in research?
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.
How do you describe variables in research?
A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.
How important is variable in research?
The importance of dependent and independent variables is that they guide the researchers to per sue their studies with maximum curiosity . ... Dependent and independent variables are also important because they determine the cause and effects in research.
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.
How do you identify a variable?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What is an example of a qualitative variable?
A qualitative variable, also called a categorical variable, is a variable that isn’t numerical. It describes data that fits into categories. For example: Eye colors (variables include: blue, green, brown, hazel).
What’s a dependent variable in science?
Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors . ... (Independent variable) causes a change in (Dependent Variable) and it isn’t possible that (Dependent Variable) could cause a change in (Independent Variable).
