Scientific Inquiry, Error and Uncertainty
Random error contributes to scatter; systematic error shifts results consistently. Good methods manage variables and quantify uncertainty where appropriate.
What to remember
- Random error causes scatter.
- Systematic error can shift all readings.
- Repeats help estimate random variation.
- Calibration can reveal systematic issues.
- Uncertainty limits precision.
Key words
random error — unpredictable variation
systematic error — consistent directional error
uncertainty — measurement limitation
calibration — checking instrument against standard
precision — closeness of repeated readings
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.
