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.

What is a dependent variable?

Back

A dependent variable is the variable that is measured or tested in an experiment, which is affected by the independent variable.

Front

What does the x-axis represent in a graph?

Back

The x-axis typically represents the independent variable.

Front

What does the y-axis represent in a graph?

Back

The y-axis typically represents the dependent variable.

Front

How do you identify the independent variable from a graph?

Back

The independent variable is usually plotted on the x-axis and is the variable that you manipulate.

Front

How do you identify the dependent variable from a graph?

Back

The dependent variable is usually plotted on the y-axis and is the variable that you measure.

Front

What is a pattern in mathematics?

Back

A pattern is a repeated or recurring sequence of numbers, shapes, or other elements.

Front

What is the purpose of a graph?

Back

A graph visually represents data to help identify trends, patterns, and relationships between variables.

Front

What is estimation in mathematics?

Back

Estimation is the process of finding an approximate value that is close enough to the right answer, often used when exact calculations are not necessary.
