Readers ask: What Does Dependent Variable Mean In Science Terms?

What is the best definition of 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.

How do you explain a dependent variable to a child?

The dependent variable is the possible outcome of the experiment; the effect. It depends on what happens to other variables in the experiment. The dependent variable is basically the part that you are changing. For example, if you want to know how much light a plant needs to grow, the amount of growth is the dependent.

What’s an independent and dependent variable in science?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. 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 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.

What are the 3 types of variables?

There are three main variables: independent variable, dependent variable and controlled variables.

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.

Can time be a dependent variable?

Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.

What is a dependent variable for dummies?

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 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 ).

How do you identify an independent variable?

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 an independent variable in research?

In research design, independent variables are those that a researcher can manipulate, whereas dependent variables are the responses to the effects of independent variables. By purposefully manipulating the value of an independent variable, one hopes to cause a response in the dependent variable.

What is the uses of dependent variables?

The term “ dependent variable ” is self-explanatory because dependent variables are said to be reliant on other variables and values. Such a dependency is studied, observed, and determined through experiments and hypothesis testing. It is used to test if a statement regarding a population parameter is correct.

Is smoking a dependent or independent variable?

For example, in the research on cigarette – smoking and lung cancer, cigarette – smoking, which has already been done by many subjects, is the independent variable.” (Kerlinger, 1986, p.
