WebThis bar is drawn above and below the point (or from side to side) and shows the uncertainty in that measurement. In the example shown below (Figure 1) we will assume that only quantity A has an uncertainty and that this is +/- 1. Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement. They give a general idea of how precise a measurement is, or conversely, how far from the reported value the true (error free) value might be. Error bars often represent one standard deviation of uncertainty, one standard error, or a particular confid… free images pink roses
