Abstract
The punched-card method is illustrated, with a description of the procedures used in analyzing the data on single cotton fibers. The samples were tested for 7 properties, from which 5 more were derived by computation. For each of these 12 properties there were prepared a histogram showing the distribution of the property values within variety groups, means and standard devi ations for 6 subgroups within each variety, and a three-factor analysis of variance of the means for all varieties and subgroups. The steps in obtaining these results from the punched cards are outlined. Some advantages of this method over the desk-calculator approach are discussed.
