Refers to the closeness of a measured value to a standard value Accuracy
Refers to the closeness of two or more measurements to each other Precision
These error arise due to flaws of experimental system. There errors are eliminated by detecting the source of the error Systematic Error
It can only be reduced and the error can be estimated by using some statistical operations. Random Error
Range of possible values within which the true value of the measurements lies Uncertainty
