RANDOM ERROR
Random errors may arrise due to random and unpredictable variations in experimental conditions like pressure ,temperature ,voltage supply etc.,
example suppose you measure the mass of a ring three times using the same balence and get slightly different values
15.46kg,15.42kg,15.2kg
HOW IT CAN BE REDUCED
Take more data.Random errors can be evaluated through statistical analysis and can be reduced by averaging over a large number of observations
hope it helps u******
