Quick Answer: What Is The Difference Between An Independent Variable And A Dependent Variable?

What is dependent 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..

Which is the dependent variable?

The dependent variable is the variable that is being measured or tested in an experiment. … The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.

How do you know what the dependent variable is?

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.

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 are some other examples of dependent and independent variables?

Independent and Dependent Variable ExamplesIn 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.More items…•Dec 1, 2019

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 examples of independent?

An example of independent is someone who lives on their own and supports themself. Free from the influence, guidance, or control of another or others; self-reliant. An independent mind. Not determined or influenced by someone or something else; not contingent.

How do you write independent and dependent variables?

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). Constant variables are also important to understand.

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).

Is stress a dependent or independent variable?

Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.

What is dependent 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.

Is the control group the dependent variable?

Control – The control is the group that serves as a standard of comparison. It is exposed to the same conditions as the experimental group, except for the variable being tested. Dependent Variable – A dependent variable is a factor that may change as a result of changes in the independent variable.

What is an independent variable in science examples?

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.
