Random error

Vedclass · Answer

(A) Random errors are unpredictable fluctuations in experimental conditions that occur during measurements. These errors can be minimized by taking a large number of observations and calculating their arithmetic mean,as the positive and negative deviations tend to cancel each other out.Systematic errors,on the other hand,are consistent,repeatable errors associated with faulty equipment or flawed experimental design (such as using defective weights). These errors cannot be reduced by increasing the number of observations because they shift all measurements in the same direction.Therefore,a large number of readings will only reduce random errors.

$A$ set of defective observation weights is used by a student to find the mass of an object using a physical balance. $A$ large number of readings will reduce:
