Quick Answer: What Is Variable In Research Example?

What are the different kinds of variables?

There are six common variable types:DEPENDENT VARIABLES.INDEPENDENT VARIABLES.INTERVENING VARIABLES.MODERATOR VARIABLES.CONTROL VARIABLES.EXTRANEOUS VARIABLES..

What do independent variables mean?

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.

How do you identify key variables in research?

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. The Instrument will measure the key variables. These key variables must be directly measured or manipulated for the research study to be valid.

What do you mean by a variable?

A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

How do you describe a variable?

A variable is something that can be changed. In computer programming we use variables to store information that might change and can be used later in our program. For example, in a game a variable could be the current score of the player; we would add 1 to the variable whenever the player gained a point.

What is a variable in research?

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 the types of variable 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.

What is dependent variable in biology?

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.

What are the two types of qualitative variables?

Qualitative variables are divided into two types: nominal and ordinal.

What are the two basic types of variables in statistics?

Categorical variables can be sub-classified as nominal or ordinal with ordinal variables have a natural ordering, whereas nominal variables do not. Gender, Diabetes and Race/Ethnicity were nominal categorical variables, they have no natural order and individuals can only be put into categories for these variables.

What are the characteristics of variables in research?

Variables: Types and CharacteristicsDiscrete Variable – only a finite or potentially countable set of values.Continuous Variable – an infinite set of values between any two levels of the variables. … Independent Variable – a stimulus variable which is chosen by the researcher to determine its relationship to an observed phenomena.More items…•

What is variable and its types in statistics?

Common Types of Variables. Categorical variable: variables than can be put into categories. … Dependent variable: the outcome of an experiment. As you change the independent variable, you watch what happens to the dependent variable. Discrete variable: a variable that can only take on a certain number of values.

What are 3 types of 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. The independent variable is the one that is changed by the scientist.

What is independent variable in Research example?

The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. Two examples of common independent variables are gender and educational level.

Why do we use variables in research?

While the variation of an independent variable will influence the variation of dependent variable, both variables give the study a focus. … Dependent and independent variables are also important because they determine the cause and effects in research.

What is dependent and independent variable in Research example?

Here are some other examples of dependent and independent variables in scientific experiments: A scientist studies the impact of a drug on cancer. The independent variables are the administration of the drug – the dosage and the timing. The dependent variable is the impact the drug has on cancer.

What is variable example?

In mathematics, a variable is a symbol or letter, such as “x” or “y,” that represents a value. … For example, in the equation below, y is the “dependent variable” because its value is based on the value assigned to the “independent variable” x.

What are the two types of variables?

Types of variables.Independent vs dependent.Confounding variables.

How do you identify independent and dependent variables?

Independent and dependent variablesThe independent variable is the cause. Its value is independent of other variables in your study.The dependent variable is the effect. Its value depends on changes in the independent variable.

What are the uses of variables?

In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.
