What is meant by dependent and independent variables?
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. The dependent variable is the effect. Its value depends on changes in the independent variable.
What are examples of dependent and independent?
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.
How do you identify independent and dependent variables?
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 dependent and independent variable in differential equation?
The order of a differential equation is the order of the highest derivative that appears in the relation. The unknown function is called the dependent variable and the variable or variables on which it depend are the independent variables.
Which is 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.
Is temperature a dependent variable?
A dependent variable relies (depends) on other variables to get its value. An independent variable doesn’t rely on any others to get its value. So, the temperature is dependent, and the time is independent. If you’re looking at a graph, the independent variable is generally on the horizontal axis.
What are examples of dependent variables?
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 dependent variable in psychology?
The dependent variable is the variable that is being measured or tested in an experiment. In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable.
How do you find the 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.
Which variable is the dependent variable?
independent variable
The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).
What is the meaning of the dependent variable?
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).
