What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

In an experiment, what are control variables?

Back

Control variables are the factors that are kept constant to ensure a fair test.

What is the purpose of an experiment?

Back

The purpose of an experiment is to test a hypothesis by manipulating the independent variable and observing the effect on the dependent variable.

What is an example of an independent variable?

Back

An example of an independent variable is the amount of time spent studying when testing its effect on test scores.

What is an example of a dependent variable?

Back

An example of a dependent variable is the test scores when testing the effect of study time.

Front

Why is it important to control variables in an experiment?

Back

Controlling variables is important to ensure that the results are due to the independent variable and not other factors.

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.
