Elena investigated whether toddlers' cooperation levels differed depending on the type of play they engaged in. She used an opportunity sampling technique at a local daycare.
Elena asked one group of toddlers to engage in 15 minutes of constructive play (using wooden building blocks) (Condition A), and a different group of toddlers to engage in 15 minutes of structured play (playing a simple board game) (Condition B). Afterwards, she observed and rated their cooperative behaviors during clean-up time.
Elena used an independent groups design in her investigation.
Explain one strength of Elena using an independent groups design.
