Quizplus · Accepted Answer

Eline is planning an experimental design where she will have two groups - one with scented candles and one without - and will manipulate the presence of candles to see if it impacts heart rate, which is the dependent variable. This design allows Eline to establish cause-and-effect relationships between the independent variable (scented candles) and the dependent variable (heart rate).
