Random error

Vedclass · Answer

(A) Random errors are caused by unpredictable fluctuations in experimental conditions or observational limitations. These errors can be positive or negative and tend to cancel each other out when a large number of readings are taken and averaged.Systematic errors,on the other hand,occur due to a consistent flaw in the measuring instrument or the method of measurement (such as using defective weights). These errors are consistent in magnitude and direction and cannot be reduced by increasing the number of observations.Therefore,taking a large number of readings will only reduce the random error.

$A$ 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:
