The statement in Eq. 1 says that if we make a measurement of X, it is likely. to fall within the range (X. best. - Î´X) to (X. best. + Î´X). To represent this measurement graphically, the best. estimate of the value is denoted by a data point, and the uncertainty Â±Î´X is indicated by error bars drawn on. both sides of the measured value. Alternatively, with some algebraic manipulation, Eq. 1 can be written as. ! X = X. best  1Â±. #X.
