Experimental Design

Front

What do you call the things you MUST keep the same to make sure your results are reliable and fair?

Back

Constants are the factors that remain unchanged throughout an experiment to ensure that the results are valid and reliable.

Front

What is the variable in an experiment that is deliberately changed by the scientist?

Back

The independent variable is the factor that is intentionally altered in an experiment to observe its effect.

Front

What is a quantitative assessment?

Back

A quantitative assessment is a measurement that can be expressed numerically, such as 'He is 6 feet 8 inches tall'.

Front

What is the factor that an experimenter changes on purpose?

Back

The independent variable is the factor that is changed intentionally in an experiment.

Front

In a graph, what is the dependent variable?

Back

The dependent variable is the outcome that is measured in an experiment, such as 'Number of Deer'.

Front

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.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured in an experiment and is affected by the independent variable.

Front

What are control variables?

Back

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

Front

What is the purpose of a control group in an experiment?

Back

A control group is used as a benchmark to compare the effects of the independent variable.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.
