Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is a variable that stands alone and is not affected by other variables. It is the variable that is changed or controlled in a scientific experiment.

What is a dependent variable?

Back

A dependent variable is a variable that depends on other factors. It is the variable that is measured in an experiment.

In the equation m = 8p, what does 'm' represent?

Back

In the equation m = 8p, 'm' represents the money earned in dollars.

In the equation m = 8p, what does 'p' represent?

Back

In the equation m = 8p, 'p' represents the number of pizzas delivered.

Front

Which variable is the independent variable in the equation m = 8p?

Back

The independent variable in the equation m = 8p is 'p' (number of pizzas delivered).

Front

Which variable is the dependent variable in the equation m = 8p?

Back

The dependent variable in the equation m = 8p is 'm' (money earned).

What does it mean when we say a variable is 'dependent'?

Back

A dependent variable is one that changes in response to the independent variable. It is dependent on the value of the independent variable.

Front

What does it mean when we say a variable is 'independent'?

Back

An independent variable is one that is manipulated or changed in an experiment to observe its effect on the dependent variable.

If the number of boxes sold increases, what happens to the money collected if the price per box is constant?

Back

If the number of boxes sold increases, the money collected will also increase, assuming the price per box remains constant.

In a scientific experiment, what is the purpose of identifying independent and dependent variables?

Back

Identifying independent and dependent variables helps to clarify the relationship between them and allows for a better understanding of how changes in one variable affect the other.
