How do you explain independent and dependent 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. 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 an independent variable in science easy definition?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable.
What are independent and dependent variables examples?
Two examples of common independent variables are age and time. They’re independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It’s what changes as a result of the changes to the independent variable.
What is the use of independent variables?
Independent variables are variables that stand on their own and aren’t affected by anything that you, as a researcher, do. You have complete control over which independent variables you choose. During an experiment, you usually choose independent variables that you think will affect dependent variables.
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 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. |
Which is the best definition of a dependent variable?
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. It is the presumed effect. Independent Variable.
How is a dependent variable recorded in an experiment?
The dependent variable is ‘dependent’ on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded. When you take data in an experiment, the dependent variable is the one being measured.
What is the independent variable for kids?
Independent Variable. An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant receives.
When does an independent variable cause an effect?
If you write out the variables in a sentence that shows cause and effect, the independent variable causes the effect on the dependent variable. If you have the variables in the wrong order, the sentence won’t make sense. Independent variable causes an effect on the dependent variable.
