Golf
Drives, putting, slopes, and scoring averages.
7 formulas
Scoring Average
Mean strokes per round over a tournament or season.
Fairways Hit Percentage
Share of par 4 and par 5 tee shots that finished in the fairway.
Putts Per Round
Average number of putts per 18-hole round.
Drive Carry Model
A teed shot climbs and falls on a parabola until it lands (carry is horizontal distance to landing).
Putting Slope Angle
Steepness of a green between two points. Rise over run is the slope ratio; arctangent (arctan, inverse tangent) turns that ratio into an angle in degrees.
Score Differential (WHS)
Compares one adjusted round to course difficulty using slope and course rating from the scorecard. The 113 is the standard slope; harder courses have higher slope ratings. Posted rounds feed your Handicap Index in GHIN or your golf association.
Course Handicap (WHS)
Turns your Handicap Index (GHIN or league file) into strokes you may subtract today on this course and tees, using slope rating, course rating, and par from the scorecard.
About sports math
Sports math applies real formulas to the games students follow—batting average and ERA in baseball, shooting percentages in basketball, passer rating in football, xG and group-stage points for World Cup Seattle 2026 soccer, plus golf and volleyball stats and the physics of speed, distance, and projectile motion.
Each sport pairs a plain-language formula with a calculator and links to the Formula Library, turning stats and game situations into approachable practice for ratios, percentages, and algebra.
