An environmental psychologist conducted a correlational study to investigate the relationship between physiological stress and nature immersion in a sample of 35 forest rangers.
Physiological stress was assessed by measuring the salivary cortisol concentration of each participant, recorded in micrograms per deciliter (μg/dL\mu\text{g/dL}μg/dL). Nature immersion was determined by tracking the total duration, in minutes, that each ranger spent listening to uninterrupted natural soundscapes during their shifts.
Explain why the data collected in this study is an example of quantitative data.
