Table  Description
1 Three stages in the preparation of visual-analysis cards - blank form ready for transcription, transcribe card, and coded and slotted card
2 Three cards each representing a farm and farm family. All of the information used in the study concerning the farm and the operator's family is carried on one card
3 Pack of slotted cards before beginning exploratory studies of relationships
4 Sorting slotted cards by means of a needle
5 Cards sorted to show the relationships existing between size of farm and selected characteristics
6 Cards designed primarily for visual-analysis purposes
7 Cards sorted first by size of farm, then each size group halved to illustrate the stability of the relationships visible
8 Cards sorted to show the effect of tenure on size of farm, also, that some characteristics related to size of farm are not affected by tenure
9 Graphic illustration of the changes in number of farms by tenure which accompany changes in the size of farms used in these examples
10 Farms reporting automobiles compared with those not reporting automobiles. In these examples characteristics associated with large farms rarely appear on cards representing farms not reporting automobiles
11 Graphic illustration of the proportions shown in figure 10
12 Cards representing farms reporting trucks are shown below the heavy line
13 Relative lengths of bars indicate the changing proportions in these examples of farms reporting trucks in six size-of-farm groups
14 Cards sorted to separate farms reporting tractors from those not reporting tractors. Cards used in these examples show most of the smaller farms in the nontractor group
15 Bar graph showing, for the farms represented by the cards in figure 14, the increase in proportion reporting tractors as the size of farms increases
