Solution
Correct Answer:
Spread due to random errors
The Standard Deviation (σ) is a statistical measure of the dispersion or 'spread' of data around the mean.
- In physics experiments, it estimates the magnitude of random errors.
- Usually, a result is reported as xˉ±σ, where σ indicates the uncertainty interval.
This hard difficulty physics question is from the chapter experimental skills and error analysis, covering the topic of standard deviation hard. It appeared in the 2025 exam.
