Hitting efficiency, serve receive, sideouts, and court 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 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.
8 formulas
Hitting efficiency: kills (attacks that score) minus errors (attacks that give the other team a point), divided by total attempts.
Share of attack attempts that end in a kill (a point on that swing), without subtracting errors.
When the other team serves, sideout % is how often you win the rally and get to serve next.
Mean pass quality score (often 0–3 scale: 0 = ace against, 3 = perfect pass) divided by passes graded.
Straight-line distance across a full court rectangle (NCAA full court 60 ft by 30 ft; each side is 30 ft by 30 ft).
Steepness of an approach jump path from horizontal run to vertical rise (arctangent turns rise over run into degrees).
How far your contact point is above the net tape (women's net often 7 ft 4⅛ in, about 88 inches).
A float or jump serve rises and falls on a parabola until it crosses the net or lands in the court.
