Assessment Independent and Dependent Variables

Front

What is the independent variable in an experiment?

Back

The 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 the dependent variable in an experiment?

Back

The dependent variable is the variable that is measured and affected in an experiment, depending on 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 vertical line test determine about a graph?

Back

The vertical line test determines if a graph represents a function by checking if any vertical line intersects the graph at more than one point.

Front

If a graph shows a straight line, what can be inferred about the relationship between the variables?

Back

A straight line indicates a linear relationship between the independent and dependent variables.

Front

In the equation m = k * d, what does 'm' represent?

Back

In this equation, 'm' represents the amount of money raised, which is dependent on the distance 'd' walked.

Front

What is a function in mathematical terms?

Back

A function is a relation where each input has exactly one output.

Front

What does it mean if a graph has repeating input values?

Back

If a graph has repeating input values, it does not represent a function.

Front

What is an example of a dependent variable in a real-life scenario?

Back

An example of a dependent variable is the height of a plant, which depends on the amount of sunlight it receives.
