Unit 3 Experimental Design pre-test

Front

What is an independent variable?

Back

An independent variable is the factor in an experiment that is changed or controlled to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

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

Front

What are constants in an experiment?

Back

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

Front

What is a control group?

Back

A control group is the part of an experiment that does not receive the independent variable and is used for comparison.

Front

Why is it important to have only one independent variable in an experiment?

Back

Having only one independent variable helps to isolate the effects of that variable, making the results clearer and more valid.

Front

What is the purpose of an experimental group?

Back

The experimental group is the part of the experiment that receives the independent variable, allowing researchers to observe its effects.

Front

What is the scientific method?

Back

The scientific method is a systematic process for conducting experiments and making observations to answer questions.

Front

What is a hypothesis?

Back

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

Front

What is the difference between qualitative and quantitative data?

Back

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

Front

What is the importance of replicating experiments?

Back

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.
