<p><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Para determinar la nota que representa al «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»50«/mn»«mo»%«/mo»«/math» de los alumnos con las notas más altas, tenemos que tener en cuenta que el concepto asociado a esto es la Mediana.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Recuerda que debemos ordenar los datos de forma creciente y ubicar el o los datos que se encuentran en las posiciones centrales.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Si la cantidad de datos es impar quedará un sólo valor central el cual corresponde a la mediana y si la cantidad de datos es par se deben promediar los dos valores centrales.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Comenzamos determinando el tamaño de la muestra (cantidad de alumnos del curso), esto lo logramos sumando todas las frecuencias.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Realizado esto, concluimos que hay #n alumnos.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">#retro2</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Por lo tanto la Mediana corresponde a la nota #sol.</span><br /><br /><br /></p>
