assesment task 2

Question 1

Accuracy

Answer 1

accuracy is about making sure that the data you collect in your experiments is as close as possible to the real or expected values. To achieve this, you use the right tools, equipment, and methods, and you double-check your results to avoid mistakes.

Question 2

Validity

Answer 2

Validity is about making sure that your experiment is actually testing what you intend to test. This is achieved by controlling variables

Question 3

Reliability

Answer 3

Reliability is about how consistent your results are. If you do the same experiment multiple times, you should get similar results each time.

Question 4

Precision

Answer 4

Precision refers to how close your measurements are to each other when you repeat them.

Question 5

Random error

Answer 5

Random error is the kind of mistake or variation that happens without any pattern, usually because of small, unpredictable factors.

Question 6

Systematic error

Answer 6

Systematic error is a mistake that happens in the same way every time. It’s often caused by a problem in the system (like a faulty instrument).

Question 7

RAVES

Answer 7

RAVES stands for Reliability, Accuracy, Validity, Ethics, and Safety — key things to consider when writing a method.

Question 8

Charles’ Law

Answer 8

Charles’ Law is a principle in physics that says that the volume of a gas increases as the temperature increases at constant pressure.

Question 9

Boyle’s Law

Answer 9

Boyle’s Law states that as the pressure of a gas increases, the volume decreases at constant temperature.
