Independent/Dependent & Additive/Multiplicative

Front

What is an independent variable?

Back

An independent variable is a 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, depending on the independent variable.

Front

What does an additive relationship mean?

Back

An additive relationship means that the output (y) increases by a constant amount as the input (x) increases.

Front

What does a multiplicative relationship mean?

Back

A multiplicative relationship means that the output (y) increases by a constant factor as the input (x) increases.

Front

In the equation x + 3 = y, what type of relationship is represented?

Back

Additive and the graph would NOT cross through the origin.

Front

In the equation 2x = y, what type of relationship is represented?

Back

Multiplicative and the graph would cross through the origin.

Front

What is the graph of an additive relationship like?

Back

The graph of an additive relationship is a straight line that does not pass through the origin.

Front

What is the graph of a multiplicative relationship like?

Back

The graph of a multiplicative relationship is a straight line that passes through the origin.

Front

If 'Minutes' is the independent variable in a table, what does that mean?

Back

It means that 'Minutes' is the variable that is controlled or changed to see how it affects the dependent variable.

Front

What are independent quantities?

Back

Independent quantities are values that are not affected by other variables in the experiment.
