                                   Error of Measurement






                                      • Example  2.55, 2.67, 2.66, 2.60, 2.62



                                      • Mean ( x )                                             =  2.62



                                      • Standard deviation, σ  =  0.049



                                            % Error (variation)                               = (σ/ x ) x 100 %



                                                                                               = 1.87%
