This study analyzed the putting strokes of amateur golfers to examine the interaction between effective loft and predicted spin. The hypothesis was verified by putting data analyzed using SAM PuttLab. The effective loft average of the group (n=17) with the predicted spin is -.647 (SD=1.646), with an effective soft average of 1.369 (SD=1.162) for the neutral spin group (n=16), and an effective soft average of 4.077 (SD=2.313). The overall average of effective loft was 2.145 (SD=2.76), and the minimum value was zero and the maximum value was 9.7. In addition, it has been found that both the skewness and kurtosis of effective loft do not exceed the absolute value of 2 constitute a normal distribution. A peason correlation analysis has shown that the statistical significance between effective loft and predicted spin is interrelated (r=.729), i.e. 0.729 between effective loft and predicted spin, which is significant at 99% confidence levels. A group of criteria categories was selected through the multinomial logistic Reg. procedure to verify statistical significance. Effective loft was found to be 3.007 times higher stochastic when the predicted spin is neutral spin than top spin (p=.005, Exp(B)=3.007). This explains that the lower the effective loft, the better the ball can roll in roll resistance. Effective loft was found to be 7.801 times higher stochastic when the predicted spin was back spin than top spin (p=.000, Exp(B)=7.801).
