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 is dependent and independent variable in research example?
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. … The independent variable in your experiment would be the brand of paper towel.
What is dependent variable and independent variable in research?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. … The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
What is dependent variable explain with examples?
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.
How do you explain a dependent variable?
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.
Can time be a dependent variable?
Time is always the independent variable. The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).
What are the 3 types of variables?
These changing quantities are called 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.
How do you find the independent and dependent variable in a sentence?
You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis).
What is a sentence for dependent variable?
Two multiple regression analyses were performed with each contraceptive measure as a dependent variable. The dependent variable here was equal to 1 if the women had ever used a medical method and zero otherwise.
What is dependent and independent variable in qualitative research?
The independent variable is the variable that is being manipulated, or the one that varies. It is sometimes called the ‘predictor’ or ‘treatment’ variable. The dependent variable is the outcome (or response) variable.
Which is a good example of a 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 is variable in Research example?
In research, variables are any characteristics that can take on different values, such as height, age, species, or exam score.
What is another name for dependent variable?
The other name for the dependent variable is the Predicted variable(s). The dependent variables are named as such because they are the values that are predicted or assumed by the predictor / independent variables.
What is independent variable in biology?
Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
What is an example of a moderating variable?
A moderating variable is a type of variable that affects the relationship between a dependent variable and an independent variable. … For example, suppose we want to fit a regression model in which we use the independent variable hours spent exercising each week to predict the dependent variable resting heart rate.
Why are independent and dependent variables important?
Dependent and independent variables are important because they drive the research process. … Dependent and independent variables are also important because they determine the cause and effects in research.
