Media armónica Tutorial
 Media armónica Definición:      La media armónica se utiliza para calcular la media de un conjunto de números. Aquí el número de elementos será promediado y divido entre las suma de los recíprocos de los elementos. La media armónica siempre es la media más baja. Media armónica fórmula : Media armónica = N/(1/a1+1/a2+1/a3+1/a4+.......+1/aN) donde               X = La puntuación individual               N = Tamaño de la muestra (Número de resultados) Warning: include(../tutorial-ad.txt) [function.include]: failed to open stream: No such file or directory in /home/easy/public_html/es/statistics/learn-harmonic-mean.php on line 48 Warning: include(../tutorial-ad.txt) [function.include]: failed to open stream: No such file or directory in /home/easy/public_html/es/statistics/learn-harmonic-mean.php on line 48 Warning: include() [function.include]: Failed opening '../tutorial-ad.txt' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/easy/public_html/es/statistics/learn-harmonic-mean.php on line 48 Media armónica Ejemplo:Para encontrar la media armónica de la 1,2,3,4,5.   Paso 1: Calcula el número total de valores.             N = 5   Paso 2: Ahora determina la media armónica utilizando la fórmula de arriba.             N/(1/a1+1/a2+1/a3+1/a4+.......+1/aN)             = 5/(1/1+1/2+1/3+1/4+1/5)             = 5/(1+0.5+0.33+0.25+0.2)             = 5/2.28             Tan, Media armónica = 2.19 Este ejemplo le guiará para calcular la media armónica de forma manual.
