Abstract: Although the use of histograms implies loss of information due to the fact that the actual data are replaced by the central values of the considered intervals, these graphical representations are commonly employed in scientific communication, particularly in astrophysics. This work explores the possibility of applying the Anderson-Darling test, a well-known test suitable for the comparison of continuous data sets, to the comparison of data in histogram format. For that purpose the data within each histogram interval are resampled, using the information provided by the frequencies of the adjacent intervals. Several resampling strategies have been examined by the comparison of histograms built from simulated data following a normal distribution.
