Descripci\u00f3n General<\/h2>\n

La funci\u00f3n T.DIST.2T en Excel y DISTR.T.2C en Google Sheets es una herramienta estad\u00edstica que calcula las probabilidades de las dos colas de la distribuci\u00f3n t de Student. Es frecuentemente utilizada en pruebas de hip\u00f3tesis, particularmente \u00fatil para comparar las medias de dos muestras independientes con varianzas desconocidas y posiblemente distintas, y es especialmente valiosa cuando el tama\u00f1o de la muestra es reducido.<\/p>\n

Sintaxis y Ejemplos<\/h2>\n

La sintaxis de la funci\u00f3n en Excel es:<\/p>\n

T.DIST.2T(x, grados_libertad)<\/code><\/pre>\n
En Google Sheets, la sintaxis es muy similar:<\/p>\n
DISTR.T.2C(x, grados_libertad)<\/code><\/pre>\n
Donde:<\/p>\n
    \n
  • x<\/strong> es el valor t, calculado como la diferencia entre la media de la muestra y la media de la poblaci\u00f3n, dividida por el error est\u00e1ndar de la media.<\/li>\n
  • grados_libertad<\/strong> son los grados de libertad de la muestra, usualmente igual a n<\/em> – 1, donde n<\/em> es el n\u00famero de observaciones en la muestra.<\/li>\n<\/ul>\n
    Ejemplo de uso:<\/p>\n
    Consideremos un investigador con una muestra de 25 observaciones, donde el valor t es 2.3. Si desea calcular la probabilidad de obtener un valor t igual o m\u00e1s extremo que 2.3 en ambas direcciones de la cola, utilizar\u00eda:<\/p>\n\n\n\n\n
    Software<\/th>\nF\u00f3rmula<\/th>\nResultado<\/th>\n<\/tr>\n
    Excel<\/td>\n=T.DIST.2T(2.3, 24)<\/td>\n0.0297<\/td>\n<\/tr>\n
    Google Sheets<\/td>\n=DISTR.T.2C(2.3, 24)<\/td>\n0.0297<\/td>\n<\/tr>\n<\/table>\n
    Aplicaciones Pr\u00e1cticas<\/h2>\n
    Tarea 1: Comparaci\u00f3n de Promedios de Ex\u00e1menes<\/h3>\n
    Dos grupos de estudiantes, uno con n=30 y otro con n=28, han sido evaluados bajo diferentes metodolog\u00edas de ense\u00f1anza, obteniendo promedios de 78 y 74 respectivamente. El investigador utiliza la funci\u00f3n T.DIST.2T o DISTR.T.2C para determinar si hay diferencias significativas entre ambos promedios al 95% de confianza.<\/p>\n
    # C\u00e1lculo manual del valor t t = (78 - 74) \/ sqrt((5^2\/30) + (7^2\/28)) = 2.23 # F\u00f3rmula en Excel =T.DIST.2T(2.23, 56) # F\u00f3rmula en Google Sheets =DISTR.T.2C(2.23, 56) <\/code><\/pre>\n
    Si el p-value es menor a 0.05, se concluye que las diferencias son significativas.<\/p>\n
    Tarea 2: Evaluaci\u00f3n de Resultados de Medicamentos<\/h3>\n
    Al evaluar un nuevo medicamento en 15 pacientes, el investigador busca determinar si existe un cambio significativo en la presi\u00f3n arterial antes y despu\u00e9s de su administraci\u00f3n.<\/p>\n
    # Supongamos que el valor t calculado previamente es 1.76 # F\u00f3rmula en Excel =T.DIST.2T(1.76, 14) # F\u00f3rmula en Google Sheets =DISTR.T.2C(1.76, 14) <\/code><\/pre>\n
    Un p-value menor que 0.05 sugerir\u00eda un efecto significativo del medicamento sobre la presi\u00f3n arterial.<\/p>\n","protected":false},"excerpt":{"rendered":"
