A reseаrcher аpplies vаrying amоunts оf fertilizer (0, 2, 4, 8, 10 units) tо 50 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 produced the largest tomato yield. Is the study presented above a controlled experiment?
