In a controlled experiment, the researcher typically manipulates one variable, called the independent variable, to determine how

this variable affects the final outcome, called the dependent variable. In the following hypothetical example, a researcher applies varying amounts of fertilizer (0, 2, 4, 8, 10 units) to potted tomato plants. All other variables that may affect the outcome (watering, temperature, sunlight, plant size, etc.) are kept the same from pot to pot. At the end of the growing season, the tomatoes grown on each plant are weighed to determine which fertilizer level produces the largest tomato yield. Which variable was the independent variable and which was the dependent variable?
a. Independent = Fertilizer amount, Dependent = Temperature
b. Independent = Temperature, Dependent = Yield
c. Independent = Fertilizer amount, Dependent = Yield
d. Independent = Yield, Dependent = Fertilizer amount

Answer:

c. Independent = Fertilizer amount, Dependent = Yield

Explanation:

In an experiment, the independent variable is changed to observe its effect on the dependent variable. In the given experiment, the potted tomato plants were treated with different amounts of fertilizer to observe the effect of the amount of fertilizer on the plant yield. Therefore, the amount of fertilizer is an independent variable here. Since the effect of change in the amount of fertilizer was observed in terms of plant yield, the "plant yield" is a dependent variable in the experiment.
