What is the independent and dependent variable in psychology?
What is the independent and dependent variable in psychology?
The independent variable is the variable that is controlled and manipulated by the experimenter. The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the dependent variable.
How do you identify independent and dependent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
What are the types of variables in psychology?
Types of Variable
- Qualitative Variables.
- Quantitative Variables.
- Discrete Variable.
- Continuous Variable.
- Dependent Variables.
- Independent Variables.
- Background Variable.
- Moderating Variable.
How do you identify IV and DV in psychology?
In an experiment, the IV is a variable that is changed to see how it affects something else, whereas the DV is a variable that is being measured/observed. The DV is assumed to be affected by the IV, hence the term ‘dependent’ (its value depends on the state of the IV).
Which is the dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment. 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 examples of independent and dependent 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 is an example of a dependent variable in psychology?
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.
How do you identify 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 are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What are the different types of variables and its uses?
Parts of the experiment: Independent vs dependent variables
| Type of variable | Definition |
|---|---|
| Independent variables (aka treatment variables) | Variables you manipulate in order to affect the outcome of an experiment. |
| Dependent variables (aka response variables) | Variables that represent the outcome of the experiment. |
What are some examples of dependent variables in psychology?
A researcher is interested in studying how the amount of time spent studying influences test scores.
What is the difference between an independent variable and a dependent variable?
In science and math, an independent variable is a variable or value that is changed, altered, or entered, while a dependent variable is a variable or value that is being observed. You may manipulate or control independent variable, but the dependent variable cannot be touched and can simply be examined.
How do you determine independent and dependent variables?
Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis.
What is the independent variable in psychology?
The independent variable is the characteristic of a psychology experiment that is manipulated or changed. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
