Luego establecido el intervalo modal ( 1 i L - , i L ], la moda Mo se calcula como 1 i Mo L m - = + . Y para averiguar m nos basamos en que los triángulos ´ B AB y ´ CAC son semejantes verificando que: 1 1 i i i i i a m m h h h h - + - = - - Quitando denominadores: 1 1 1 ( ) i i i i i i i h m h m h m h m h h a + - - - = - + + - 1 1 1 (2 ) ( ) i i i i i i h h h m h h a - + - - - = - . Despejando en la última igualdad obtenemos 1 1 1 2 i i i i i i h h m a h h h - - + - = - - , que es el valor buscado.
