Raul wants to know which species of grass will grow best in his yard. He plants four different types and waters them according to the directions on the package. All four receive the same amount of sunlight and are planted in the same type of soil. After a few days, he begins to see a difference in how fast the different types of grass are growing. What is the outcome variable (dependent variable) in Raul's investigation? Group of answer choices the light and water each type received the type of grass seed planted the speed at which each type grew the cost of each type of grass seed

Explanation: The dependent variable couod be explained as the response variable which is usually controlled by the explanatory or independent variable. The outcome of the dependent variable lies on the variation in the independent or explanatory variables. In the scenario above, the independent or explanatory variable is the different species of grass planted. These variation leads to the difference in growth rate experienced by the plants, the speed at which they grow is the dependent variable, since it is the result of the variation in the independent (grass species) variable.
