What is an independent variable?

Back

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

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 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 results are due to the independent variable.

Front

What is the purpose of a control group?

Back

A control group is used as a standard for comparison in an experiment, helping to isolate the effects of the independent variable.

Front

What does it mean to conduct a fair test?

Back

Conducting a fair test means ensuring that only one variable is changed at a time while all other conditions remain the same.

Front

What is the role of a hypothesis in an experiment?

Back

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

Front

How do you determine the outcome of an experiment?

Back

The outcome of an experiment is determined by analyzing the data collected from the dependent variable.

Front

What is the significance of repeating experiments?

Back

Repeating experiments helps to verify results and ensure that they are reliable and not due to chance.

Front

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 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).
