Abstract
Extensive analysis of specific inventory-item information on large numbers of any extended form by ordinary methods would be practically impossible due to the volume and labor involved. To overcome this obstacle it is necessary to put the data into a form in which large numbers of completed inventories can be item analyzed easily and quickly but without losing completeness and individuality. A system using IBM punch cards seemed to meet all of these conditions when a counting or statistical sorter is available. The IBM punch card, as shown in Figure 1, is known to most research workers. Data, after having been converted into numerical or alphabetical form, can be economically recorded on the card. The cards can then be easily sorted and the information thereon reproduced, tabulated and cross-tabulated in a variety of ways as needed. Complete intercorrelations, multiple correlations and even factor analysis may be computed with very little resort to ordinary calculators.
