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. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
What is independent and dependent variable in psychology?
Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships. The 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 is an example of a dependent variable in psychology?
An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy). In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
What are some examples of independent and dependent variables in psychology?
Let’s take the example of “Test Scores”. You want to see the effect of studying or sleeping on a test score. In the example, “test score” is the dependent variable. “Studying” or “sleeping” is the independent variable because these factors impact how much a student scores on the test.
What is an independent variable example? – Related Questions
What are the 3 types of variables in psychology?
There are three main variables: independent variable, dependent variable and controlled variables.
What is the difference between independent and dependent variables examples?
A dependent variable depends on an independent variable, while an independent variable depends on external manipulation. For example, when measuring how the speed of a car will affect the time it will take to reach a certain place, the time taken (dependent variable) depends on the speed (independent variable).
What are the 5 types of dependent variables?
Dependent Variables in Psychology.
A dependent variable is also called:
- 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 6 types of independent variables?
In statistics, an independent variable is also sometimes called:
- A controlled variable.
- An explanatory variable.
- An exposure variable (in reliability theory).
- A feature (in machine learning and pattern recognition).
- An input variable.
- A manipulated variable.
- A predictor variable.
- A regressor (in regression analysis).
What are 2 common examples of independent variable?
Two examples of common independent variables are age and time. There’s nothing you or anything else can do to speed up or slow down time or increase or decrease age. They’re independent of everything else.
Why is it called independent variable?
The independent variable is “independent” because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment.
Is gender an independent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
Is happiness a independent variable?
The dependent variable is the happiness level and independent variables include interaction terms between After disaster and Trust (fixed effects estimation) The positive relationship between trust and happiness has been demonstrated by the literature.
Can you have 2 independent variables?
Researchers often include multiple independent variables in their experiments. The most common approach is the factorial design, in which each level of one independent variable is combined with each level of the others to create all possible conditions.
Is eye color a dependent variable?
2. Design an investigaton using eye color as a dependent variable. This time eye color is the dependent variable, so you have to research things that might affect eye color. Since eye color is an inherited trait, I cannot think of any investigation that can be done.
Is IQ dependent or independent variable?
For example, take our example of 100 students completing a maths exam where the dependent variable was the exam mark (measured from 0 to 100), and the independent variables were revision time (measured in hours) and intelligence (measured using IQ score).
Is heart rate a dependent variable?
The dependent variable is your heart rate, because your heart rate depends on how fast you’re walking. That’s the outcome you want to measure in your experiment.
Is IQ dependent variable?
If we believe that intelligence influences (or explains) students’ academic achievement, then a measure of intelligence such as an IQ score is an independent variable, while a measure of academic success such as a GPA (grade point average) is a dependent variable.
Is age a continuous variable?
The age is another example of a continuous variable that is typically rounded down.
What type of variable is gender?
Categorical variables can be either ordinal (the categories can be ranked from high to low) or nominal (the categories cannot be ranked from high to low). Gender is an example of a nominal variable because the categories (woman, man, transgender, non-binary, etc.) cannot be ordered from high to low.
What are the 4 types of variables?
You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio).
