El punto crucial de la metodología de los estudios experimentales es cómo va a decidirse quiénes, entre los participantes, van a recibir el elemento nuevo que se introduce. Esta decisión puede ser dejada al azar y de manera aleatoria los sujetos participantes en el estudio se dividen en dos grupos: el experimental, formado por los receptores del nuevo factor introducido por el investigador, y el control, constituido por los restantes participantes. La aleatorización en la distribución de la intervención es lo que define a un estudio experimental como puro o verdadero. Si, por el contrario, la aleatorización no se realiza y es el investigador -influido o no por las características de la experienciael que decide quienes recibirán o no la intervención, el estudio es definido como cuasiexperimental.","PeriodicalId":186781,"journal":{"name":"Fundamentos de epidemiología","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131404327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
