  A set of objective bar-classification methods have been applied to the Ohio
State Bright Spiral Galaxy Survey (Eskridge et al. 2002). Bivariate comparisons
between methods show that all methods agree in a statistical sense. Thus the
distribution of bar strengths in a sample of galaxies can be robustly
determined. There are very substantial outliers in all bivariate comparisons.
Examination of the outliers reveals that the scatter in the bivariate
comparisons correlates with galaxy morphology. Thus multiple measures of bar
strength provide a means of studying the range of physical properties of galaxy
bars in an objective statistical sense.
