Random Error
Random errors can be reduced primarily by:
Select the correct option:
Solution
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.
