What is a dependent variable?

Back

A dependent variable is the measurable factor in an experiment that is affected by changes in the independent variable.

What is a control in an experiment?

Back

A control is a standard for comparison in an experiment, which remains constant and unchanged.

A scientific law describes what happens under specific conditions and is based on repeated experimental observations.

Front

What is a scientific theory?

Back

A scientific theory explains why or how something happens based on a body of evidence.

Front

What is the purpose of a hypothesis in an experiment?

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 replication in scientific experiments?

Back

Replication ensures that results are consistent and reliable, confirming the validity of the findings.

Front

What is a variable in scientific research?

Back

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

Front

What does it mean to control variables in an experiment?

Back

Controlling variables means keeping certain factors constant to ensure that the results are due to the independent variable.
