What is an independent variable?

Back

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

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.

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

What is the purpose of a control variable?

Back

The purpose of a control variable is to provide a standard for comparison in an experiment, helping to isolate the effects of the independent variable.

Front

What is a hypothesis?

Back

A hypothesis is a prediction or educated guess about the relationship between variables, often stated in an 'if/then' format.

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis by manipulating variables and observing the outcomes.

What does it mean to control an experiment?

Back

To control an experiment means to keep all variables constant except for the independent variable, ensuring that any changes in the dependent variable are due to the manipulation of the independent variable.
