Pafnuty Chebyshev
Pafnuty Lvóvich Chebyshev (Пафнутий Львович Чебышёв) (1821-1894) fue un matemático ruso. Su nombre se translitera también como Tchebychev, Tchebycheff, Tschebyscheff o Čebišev. Fue maestro de Andrei Markov. Es conocido por su trabajo en el área de la probabilidad y estadística. La desigualdad de Chebyshev dice que la probabilidad de que una variable aleatoria esté distanciada de su media en más de a veces la desviación típica es menor o igual que 1/a². Si μ es la media (o la esperanza matemática) y σ es la desviación típica, entonces podemos redefinir la relación como:
