A tomato farmer is comparing a new kind of fertilizer "SuperGrow" with two fertilizers "MagicGrow and "ExtraGrow." To test the the effect of the different fertilizers on the growth of his tomatoes, they use 3 plots of land, 200 square feet each. On each plot they plant 1-foot apart, 150, 2-week old, Sungold tomato seedlings. Every Monday and Thursday they turn on the watering sprinklers on his plots with equal amounts of fertilizer. At the end of the growing season they compare the yield of the plots by weighing all the tomatoes grown in each plot.
What is the responding/ dependent variable?



Answer :

Answer:

The responding/dependent variable is the yield of tomatoes in each plot.

Explanation:

In scientific experimentation, there are 2 types of variables: dependent and independent variables.

  • Independent variables are factors that remain constant because they cannot be controlled, for example, the amount of sunlight these plants receive.
  • Dependent variables are factors that we are measuring, in this case, the yield of each plot (think of it as the y-axis of this experiment. What are we measuring?) How much yield we get depends on the fertilizer we are using, in this case.
