Chebyshev's Theorem
Formulas
Σx = sum of all x values
Σx^2 = sum of squares of x values
Σy = sum of all y values
Σy^2 = sum of squares of y values
Sample mean (x̄ or ȳ) = Σx / n or Σy / n
Sample variance (s²) = Σ(x - x̄)² / (n - 1)
Standard deviation (s) = √variance
Chebyshev's interval = [x̄ - kσ, x̄ + kσ], where k is determined by the desired confidence level
