<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»25«/mn»«mo»%«/mo»«/math» de los alumnos con las notas #text1, debemos calcular el #text cuartil para datos no tabulados.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Por lo tanto, debes ordenar los datos de menor a mayor y ubicar el o los datos que se encuentren en la(s) posición(es) que correspondan al #text cuartil.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Recuerda que para ubicar la(s) posición(es) del cuartil debes multiplicar el número del cuartil por el tamaño de la muestra y dividir este producto en 4. Luego se deben promediar los dos valores que corresponden a las posiciones.</span><br /><br /><br /><span style="font-family: arial,helvetica,sans-serif; font-size: medium;">Realizado esto, concluimos que <span style="line-height: 2em;">la nota que representa al «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»25«/mn»«mo»%«/mo»«/math» de los alumnos con las notas #text1</span> es #sol</span><br /><br /></p>
