Solution
Correct Answer:
Taking repeated measurements and averaging
Random errors occur due to unpredictable fluctuations in experimental conditions (like temperature, voltage) or observer inconsistency.
- According to the Gaussian distribution, the chance of making a positive error is equal to the chance of making a negative error.
- By taking n readings, the random error is reduced by a factor of 1/n in the average value.
This easy difficulty physics question is from the chapter experimental skills and error analysis, covering the topic of random error. It appeared in the 2025 exam.
