Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured and affected in an experiment, responding to changes in the independent variable.

Front

On which axis is the independent variable plotted on a graph?

Back

The independent variable is plotted on the x-axis.

Front

On which axis is the dependent variable plotted on a graph?

Back

The dependent variable is plotted on the y-axis.

Front

What does a vertical number line represent in a coordinate plane?

Back

The vertical number line represents the y-axis.

Front

What does a horizontal number line represent in a coordinate plane?

Back

The horizontal number line represents the x-axis.

Front

In a relationship between variables, what does it mean if one variable is dependent on another?

Back

It means that the value of the dependent variable changes in response to the changes in the independent variable.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to understand the cause-and-effect relationship in the experiment.

Front

If 'Boxes Sold' is the independent variable, what could be a possible dependent variable?

Back

A possible dependent variable could be 'Money Collected'.

Front

What type of relationship is indicated if the increase in one variable results in a proportional increase in another variable?

Back

This indicates a multiplicative relationship.
