What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or manipulated in an experiment to test its effects.

Front

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.

Front

What are controlled variables?

Back

Controlled variables are the factors in an experiment that are kept constant to ensure that the test results are valid.

Front

How many independent variables should be tested in a controlled experiment?

Back

Only one independent variable should be tested at a time in a controlled experiment.

Front

What is a hypothesis?

Back

A hypothesis is an educated guess or prediction about the relationship between variables in an experiment.

Front

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

Back

The control group serves as a standard for comparison, allowing researchers to see the effect of the independent variable.

Front

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 the importance of repeating experiments?

Back

Repeating experiments is important to verify results and ensure reliability and accuracy of the findings.
