Question

A researcher conducts a 2×22	imes2 factorial experiment to measure tomato yield under two fertilizer types (Fertilizer A vs. Fertilizer B) and two watering schedules (Daily vs. Weekly). He observes the following:(i) Under Daily watering, Fertilizer A produces higher yield than Fertilizer B.(ii) Under Weekly watering, Fertilizer A produces lower yield than Fertilizer B.Which statement best describes what has occurred?

Accepted Answer

There is an interaction; the effect of fertilizer depends on the watering schedule.

Answer

There is no interaction; both factors independently affect yield.

Answer

There is a main effect of fertilizer only, because yields differ between A and B overall.

Answer

There is a main effect of watering only, because yields differ between Daily and Weekly overall.
