Experimental Design Review

Front

What is the dependent variable in an experiment?

Back

The dependent variable is what you measure or record during an experiment. It is affected by changes in the independent variable.

Front

What is a hypothesis?

Back

A hypothesis is a predicted outcome or an educated guess of what you think will happen in an experiment.

Front

What does the title of an experiment typically include?

Back

The title of an experiment usually includes the effect of the independent variable (IV) on the dependent variable (DV).

Front

What is a control in an experiment?

Back

A control is the reference or normal level used as a comparison in an experiment.

Front

What are levels in the context of an independent variable?

Back

Levels refer to the different values or settings of the independent variable that are tested in an experiment.

Front

What is an independent variable?

Back

The independent variable is the factor that you change or manipulate in an experiment to observe its effect on the dependent variable.

Front

What are constants in an experiment?

Back

Constants are the factors that remain the same throughout an experiment to ensure that the test is fair.

Front

What is the purpose of repeated trials in an experiment?

Back

Repeated trials are conducted to ensure the reliability and accuracy of the results by minimizing the effects of random errors.

Front

What is the conclusion in an experiment?

Back

The conclusion is a summary of the results of the experiment and whether the hypothesis was supported or not.

Front

What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
