What are constants (controlled variables) in an experiment?

• Variables that are changed or controlled in an experiment

• Variables that are measured in an experiment

What is quantitative data?

• Data that can be measured and written down with numbers

• Data that describes qualities or characteristics

• Data that is subjective and based on opinions

• Data that cannot be measured

What is the difference between accuracy and precision?

• Accuracy refers to how close a measurement is to the true value, while precision refers to how close measurements are to each other

• Accuracy and precision are the same

• Accuracy refers to the consistency of measurements, while precision refers to the correctness of measurements
