Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is a 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.

In a graph, which axis represents the independent variable?

Back

The x-axis represents the independent variable.

Front

In a graph, which axis represents the dependent variable?

Back

The y-axis represents the dependent variable.

Front

If the number of hours studied (h) affects test scores (s), which is the independent variable?

Back

The independent variable is the number of hours studied (h).

Front

If the number of photos added (p) affects the thickness of a scrapbook (t), which is the dependent variable?

Back

The dependent variable is the thickness of the scrapbook (t).

What equation represents the relationship between cost (c) and number of pizzas (p) if each pizza costs $5.50?

Back

c = 5.50p.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to understand the cause-and-effect relationship in an experiment.

Front

In the equation c = 5.50p, what does 'c' represent?

Back

'c' represents the total cost of the pizzas.

In the context of a graph, what does a change in the independent variable indicate?

Back

A change in the independent variable indicates how it affects the dependent variable.
