Effect of Variations of Delivery and Aim on Bowling Achievement of College Women

Abstract Four random groups of college women, novice to ten pin bowling, were taught under the four combinations of techniques resulting from two variations of delivery and two variations of point of aim. The variations of delivery were the hook and the straight ball, while the variations of point of aim were pin and spot. Comparisons of these instructional techniques based on the cumulative 24-game average indicate that superior results may be attained by teaching the spot point of aim to beginners regardless of the type of delivery, that beginners achieve just as good results when taught the hook ball delivery as when taught the straight ball, and that there is no interaction between type of delivery and type of aim.
