      abstract = {Excerpts from the report:  This circular aims to show the  application to farm-management and cost-of-production data,  of methods of analysis developed in other lines of  research, for the specific purpose of giving quantitative  expression to the relationships of the widely variable  characteristics so frequently observed.  The devices  employed are, essentially, checks on the validity of  conclusions which seem to be warranted by the body of data  understudy, as a result of the customary steps of analysis  of which grouping and averaging are the first.  They may  also be considered as measures or checks on the amount of  divergence of the data at hand from generally accepted  principles. In either case, the process of analysis throws  a spot light on the entire situation and factors often  otherwise obscure are brought out.},
