Scientific Inquiry and Uncertainty
Strong methods control variables, use suitable ranges and repeats, quantify uncertainty and distinguish random from systematic effects.
What to remember
- Repeats can reduce uncertainty in a mean from random variation.
- Systematic error is not fixed by simple repetition.
- Calibration can identify instrument offset.
- A valid method tests the intended relationship.
- Methods should be reproducible.
Key words
uncertainty — quantified measurement limitation
systematic error — consistent directional error
random variation — unpredictable scatter
validity — fitness for intended relationship
reproducibility — ability to repeat from method details
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.
