Question 1:
El grupo de control es aquel en el que no se aplica el factor que se está probando (el ingrediente secreto en este caso). Aquí, el grupo B recibió mentas regulares (sin el ingrediente secreto), por lo que es el grupo de control.
La variable independiente es el factor que se manipula o cambia en el experimento. Aquí, el tipo de menta (con ingrediente secreto o sin él) es lo que se está variando, por lo que es la variable independiente.
La variable dependiente es la que depende de la variable independiente y es la que se mide. Aquí, se mide la calidad del aliento (si está mejor o no), por lo que es la variable dependiente.
