It is scarcely to be expected that banks operating in dif- ferent regions, serving different classes of customers and fol- lowing different policies, would have uniform experience. Therefore, for each of the factors to be analyzed, we have supplemented the composite analysis for all banks by an in- dividual analysis for each bank that submitted a sufficiently large sample. These individual analyses, which are presented in Appendix B, indicate the degree of variation among banks and the extent to which the average experience of all banks typifies theexperience of any one bank. It will be seen that in some instances the individual samples differ widely from one another, and thus from.
