In a study investigating the effects of temperature and humidity on plant growth, researchers use a factorial design where temperature levels are varied at 25°C and 30°C, and humidity levels are varied at 50% and 70%. Which of the following statements about interactions is most accurate in this context?

Question

Answer

An Interaction occurs when the effects of temperature on plant growth are independent of humidity levels.

Answer

Interactions are not relevant in this experimental setup as temperature and humidity are manipulated separately.

Answer

An interaction occurs when the effect of temperature on plant growth is different depending on the level of humidity.

Answer

An interaction occurs when temperature and humidity levels are kept constant throughout the experiment.
