What is an independent and dependent variable for kids?
An independent variable is something changed on purpose in an experiment. A dependent variable in an experiment is a variable that changes depending on how the independent variable is changed.
What is an example of a common independent variable?
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 a dependent and independent variable in science experiments?
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 a real life example of independent variable?
Examples of Independent variables: 1. In an experiment to test how the amount of sunlight affects the growth of radishes. The independent variable is the amount of sunlight each plant receives. 2. In an experiment to test the effect a gasoline additive has on gas mileage in a car, the amount of additive per gallon is the independent variable.
Could You give Me an example of independent variable?
An independent variable is a variable that can be changed or modified in a scientific experiment. This is done to test the dependent variable by modifying the independent variable. An example of an independent variable is the height you drop an egg from to see if it will break .
What are examples of dependent variables?
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. An example of a dependent variable is how tall you are at different ages.
What are the types of independent variables?
Depending on the context, an independent variable is sometimes called a “predictor variable”, regressor, covariate, “controlled variable”, “manipulated variable”, “explanatory variable”, exposure variable (see reliability theory), “risk factor” (see medical statistics), “feature” (in machine learning and pattern recognition) or “input variable.”.
