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 a variable kid friendly definition?

Kids Definition of variable (Entry 2 of 2) 1 : something that changes or can be changed.

What is the difference between a dependent and independent variable in science?

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 the difference between dependent and independent variable in science?

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.

What is a dependent and independent variable in science experiments?

Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

What type of variable is age?

quantitative variable
In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old. Weight and height are also examples of quantitative variables.

How to determine an independent variable?

Method 1 of 3: Understanding Independent and Dependent Variables. Think of an independent variable as a cause that…

What makes a variable independent?

The independent variable is “independent” because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher.

How do you measure an independent variable?

The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement. In a simple mathematical equation, for example: a = b/c the independent variables, b and c , determine the value of a .

What is the difference between an independent variable and a dependent variable?

In science and math, an independent variable is a variable or value that is changed, altered, or entered, while a dependent variable is a variable or value that is being observed. You may manipulate or control independent variable, but the dependent variable cannot be touched and can simply be examined.
