La variable independiente es aquella que el investigador manipula o cambia en un experimento. En este caso, el estudiante cambia el número de semillas en cada taza, mientras que mantiene constante la cantidad de agua y la cantidad de suelo. La altura de las flores es la variable dependiente, ya que depende del número de semillas.

D. Número de semillas
