It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What is an example of dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
What are some examples of dependent and independent variables?
Independent and Dependent Variable Examples
- In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score.
- You want to compare brands of paper towels, to see which holds the most liquid.
What are the 6 types of dependent variables?
Other Names for the Dependent Variable.
- An experimental variable.
- An explained variable.
- A measured variable.
- An outcome variable.
- An output variable.
- A responding variable.
- A regressand (in regression analysis.)
- A response variable.
What are the types of dependent variables?
In statistics, dependent variables are also called: Response variables (they respond to a change in another variable) Outcome variables (they represent the outcome you want to measure)
What is the independent variable in an experiment example?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What are some examples of independent and dependent variables in healthcare?
When a researcher gives an active medication to one group of people and a placebo, or inactive medication, to another group of people, the independent variable is the medication treatment. Each person’s response to the active medication or placebo is called the dependent variable.
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself.
What is Dependant variable in research?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.
Is time a dependent variable?
Time is usually viewed as the independent variable for the simple reason that it doesn’t depend on anything else. Time simply ticks by at the same rate wherever you are (in non-relativistic context), independent of other variables so it doesn’t make sense to express time as a dependent variable.
What are the 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.
What are the 5 types of variables?
These types are briefly outlined in this section.
- Categorical variables. A categorical variable (also called qualitative variable) refers to a characteristic that can’t be quantifiable.
- Nominal variables.
- Ordinal variables.
- Numeric variables.
- Continuous variables.
- Discrete variables.
What is variable example?
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
What are the 4 types of variables?
Such variables in statistics are broadly divided into four categories such as independent variables, dependent variables, categorical and continuous variables. Apart from these, quantitative and qualitative variables hold data as nominal, ordinal, interval and ratio.
How do you create a dependent variable?
The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.
How many dependent variables should an experiment have?
A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.
Is age an independent variable?
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.
What is an independent variable in psychology example?
The independent variable is the variable that is manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.
What type of variable is gender?
nominal variable
A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories.
What is a dependent variable in healthcare?
The dependent variable is the response that is measured. For example: In a study of how different doses of a drug affect the severity of symptoms, a researcher could compare the frequency and intensity of symptoms when different doses are administered.
Is blood pressure a dependent or independent variable?
Thus, the dependent variable in the study is the measure of blood pressure. The patients blood pressure readings may or may not be affected by the independent variable, the pill, in this study.
