This study was designed to investigate the relationship between selected observable variables of age, height, weight, hand size and throwing accuracy in football. The investigation purposed to determine whether hand size had any relationship to throwing accuracy; to determine whether age, height or weight have any relationship to throwing accuracy; and to determine which variables related most closely to throwing accuracy for high school sophomore boys. One hundred sophomore boys of Downers Grove Community High School participated In this study. Conventional methods were utilized to obtain the variable measurements of age, height and weight. Tim anthropometric measures of the subjects' dominant or throwing hands; length, width and span, were obtained by use of the foot-o-graph. The foot-o-graph is an imprinting device normally used by chiropodists to record patients' foot prints for the purpose of calculating per cent of arch. Each subject was given ten consecutive throws, with a rubber Voit model CF 9 football, at a four-foot archery target from a distance of ten yards. The circled areas of the target were given varied point values with a maximum point score of fifty. All throwing attempts were recorded. The means and standard deviations of the group were obtained in the conventional manner. The relationships among the variables of age, height, weight, hand size and throwing accuracy were found by the use of the Pearson product-moment method of computing a coefficient of correlation from raw or obtained scores. The significance of this correlation was determined by means of Pisher's a transformation. The findings revealed that seven variable combinations had levels of significance from the five to the one per cent levels. The variable combination of height to weight showed the highest correlation. Other combinations at the one per cent level of significance were: hand span to weight, hand span to height and height to hand length. At the five per cent level of significance there were three variable combinations: weight to hand length, weight to hand width and weight to throwing accuracy. Weight related significantly in five of the seven variable combinations. However, the correlation was too low to merit its use as a predictive device. The data accumulated in this study revealed there was no significant relationship between hand size and throwing accuracy of the sophomore boys at Downers Grove Community High School. The null hypothesis that there was no relationship between hand size and throwing accuracy at the one per cent level of confidence was not tenable as indicated by the data.
