Spanish term or phrase: contrastes de proporciones
Teniendo en cuenta que la variable respuesta asociada a una conversación es una Bernoulli de parámetro p, se calcularan los intervalos de confianza para el verdadero parámetro p para cada uno de los partidos políticos y se distingue, como se ha mencionado en el anterior punto, entre los dos roles (profesional y no profesional de la política). Se han realizado diversos contrastes de proporciones para ver la existencia de diferencias significativas en las comparaciones pareadas con el objetivo de establecer un ranking entre las diferentes tasas de respuesta.
---
Finalmente y asumiendo que el muestreo en la extracción de la información proporcionado por twiter ha sido el adecuado, veremos si existen diferencias significativas en las diferentes tasas de respuesta para los casos anteriormente analizados de manera descriptiva. En primer lugar, se realizan contrastes de igualdad de proporciones.
