MESSAGE \u00b7 CRITICALLY EXAMINED<\/span><\/p>\n<\/div> A good range session is not training progress. Three rounds are not a trend. Ten data points are a solid rule of thumb\u2014but nothing more. What significance really means, why \u201edata-driven training\u201d is often oversold, and how senior golfers still measure accurately.<\/span><\/p><\/div><\/div><\/div><\/div><\/div> The most common pattern in senior golf: After six weeks of training, a three-circle drill suddenly goes from 27 percent to 50 percent. Enthusiasm, status update at the club, a perceived breakthrough. On the second attempt the next day: 32 percent. On the third: 40. The 50 percent value was an outlier to the upside; the rest is the real, more moderate improvement. Statistics in senior golf have one primary purpose: not to deceive oneself\u2014neither in one direction nor the other.<\/p>\n<\/div> The term \u201estatistical significance\u201d is often used casually in golf marketing\u2014usually inappropriately. Significance in the strict sense describes how unlikely an observed difference would be, assuming there is no real effect. It depends on three things: effect size, variance, and sample size. For practical application on the driving range, a much simpler question suffices: Is the data sufficient to avoid deceiving me? And the answer is almost never \u201ethree.\u201d.<\/p>\n<\/div> \u2014 Dr. Mark Broadie, Strokes-Gained researcher, Columbia Business School<\/p>\n<\/div> Three Principles of Statistical Discipline for Seniors.<\/p>\n Ten data points per KPI is the point where daily fluctuations and environmental noise smooth out.
