QUÉ SIGNIFICA CONTROL GROUP EN INGLÉS
Grupos de tratamiento y control
En el diseño de los experimentos, los tratamientos se aplican a las unidades experimentales en el grupo de tratamiento. En experimentos comparativos, los miembros del grupo complementario, el grupo de control, no reciben tratamiento ni tratamiento estándar. Para que las conclusiones obtenidas de los resultados de un experimento tengan validez, es esencial que los ítems o pacientes asignados a los grupos de tratamiento y control sean representativos de la misma población. En algunos experimentos, como muchos en agricultura o psicología, esto puede lograrse asignando al azar artículos de una población común a uno de los grupos de tratamiento y control. En estudios de gemelos que involucran sólo un grupo de tratamiento y un grupo de control, es estadísticamente eficiente realizar esta asignación aleatoria por separado para cada par de gemelos, de modo que uno está en el grupo de tratamiento y uno en el grupo de control. En algunos estudios médicos, donde puede no ser ético tratar a los pacientes que presentan síntomas, los controles pueden recibir un tratamiento estándar, en lugar de ningún tratamiento.
definición de control group en el diccionario inglés
