When performing the regression analysis, it is evident that the only significant variable is the number of top 10 finishes, with a P-value of 0.0014, which is below the 0.05 threshold. Additionally, the R-squared value of 0.8204 differs from the model that only includes top 10 finishes, which has an R-squared of 0.0860. R-squared alone cannot determine the correct model; it merely indicates the strength of the relationship between the dependent variable and the independent variables. We can conclude that the only statistically significant variable for predicting winnings is the number of top 10 finishes
