Answer

Explicación paso a paso:

Paso 1: Analizar el primer enunciado

En el enunciado "An investigation was done to see if keeping the lights on for different amount of time each day affected the number of eggs the chicken lay", la variable que se manipula (independiente - IV) es el tiempo que las luces están encendidas cada día. La variable que se mide y se espera que cambie en función de la variable independiente (dependiente - DV) es el número de huevos que ponen las gallinas. IV: Tiempo que las luces están encendidas cada día DV: Número de huevos que ponen las gallinas

Paso 2: Analizar el segundo enunciado

Para "The time it takes to run a mile depends of the amount of exercise a person gets", la variable independiente es la cantidad de ejercicio que una persona hace. La variable dependiente es el tiempo que tarda en correr una milla. IV: Cantidad de ejercicio DV: Tiempo para correr una milla

Paso 3: Analizar el tercer enunciado

En "Grass will grow taller if it is watered and fertilized more", la variable independiente es la cantidad de riego y fertilización. La variable dependiente es la altura del pasto. IV: Cantidad de riego y fertilización DV: Altura del pasto

Paso 4: Analizar el cuarto enunciado

Para "An investigation was performed to see if corn seeds would sprout at different times depending on the temperature of the air in which they were placed", la variable independiente es la temperatura del aire. La variable dependiente es el tiempo en el que los semillas de maíz germinan. IV: Temperatura del aire DV: Tiempo de germinación de las semillas de maíz

Respuesta:

  1. IV: Tiempo que las luces están encendidas cada día DV: Número de huevos que ponen las gallinas
  2. IV: Cantidad de ejercicio DV: Tiempo para correr una milla
  3. IV: Cantidad de riego y fertilización DV: Altura del pasto
  4. IV: Temperatura del aire DV: Tiempo de germinación de las semillas de maíz
