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 the x-axis represent in a coordinate plane?

Back

The x-axis represents the horizontal number line in the coordinate plane.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical number line in the coordinate plane.

Front

In the equation d = 25t, what does 'd' represent?

Back

In the equation d = 25t, 'd' represents the distance traveled.

Front

In the equation d = 25t, what does 't' represent?

Back

In the equation d = 25t, 't' represents the time in hours.

Front

If time is the independent variable, what is the dependent variable in the context of distance traveled?

Back

If time is the independent variable, the dependent variable is the distance traveled.

Front

What is the relationship between independent and dependent variables?

Back

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