Q11. How random error can be reduced?

Ans:

Random errors are unpredictable and uncontrollable errors that can happen irregularly. These errors can be caused by fluctuations in experimental conditions or
imperfections in measuring instruments.
Random errors can be reduced by increasing the number of measurements and using more precise measuring instruments.
To minimize random errors, it is important to take repeated measurements and use statistical analysis to account for the variability.
In conclusion, while random errors can never be eliminated, they can be significantly reduced by taking multiple measurements, using precise instruments, controlling experimental conditions, and using proper techniques.
