Independent vs Dependent Variables & Equations

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that is measured or observed in an experiment. It changes in response to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the variable that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

Which axis represents the independent variable in a graph?

Back

The x-axis represents the independent variable.

Front

Which axis represents the dependent variable in a graph?

Back

The y-axis represents the dependent variable.

Front

Write an equation for the scenario: A car travels at a speed of 60 miles per hour. Use x for time in hours and y for distance traveled.

Back

y = 60x

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line, indicating the rate of change of the dependent variable with respect to the independent variable.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept, the value of y when x is 0.

Front

If the amount of sunlight affects the growth of a plant, which is the independent variable?

Back

The amount of sunlight is the independent variable.

Front

If the height of a plant is measured based on the amount of water it receives, what is the dependent variable?

Back

The height of the plant is the dependent variable.

Front

What does it mean if a variable is controlled in an experiment?

Back

A controlled variable is kept constant to ensure that any changes in the dependent variable are due to the independent variable.
