Front

What is a dependent variable?

Back

A dependent variable is a variable that depends on or is changed by another variable in an experiment or function.

Front

What is an independent variable?

Back

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

Back

The independent variable is typically plotted on the x-axis.

Front

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

Back

The dependent variable is typically plotted on the y-axis.

Front

What is the output of a function called?

Back

The output of a function is called the dependent variable.

Front

In the equation y = x - 3, what is the independent variable?

Back

In the equation y = x - 3, the independent variable is x.

Front

In the equation y = 3x, what does the '3' represent?

Back

In the equation y = 3x, the '3' represents the rate of change or slope of the line.

Front

If the number of hours studied increases, what happens to the test score?

Back

The test score is likely to increase, making the test score the dependent variable.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

In an experiment, if you change the amount of sunlight a plant receives, what is the independent variable?

Back

The independent variable is the amount of sunlight.
