Approximately 70% of urban residents report feeling regularly overwhelmed by daily stressors, leading researchers to explore accessible coping mechanisms. One promising area is 'nature connectedness'—the feeling of being emotionally close to the natural world (such as noticing wildlife, listening to birdsong, or walking in parks). Psychologists want to investigate this further using a self-report survey to examine the relationship between a person's level of nature connectedness and their subjective experience of daily stress.
Suggest two variables that could be correlated in this study to investigate the relationship between nature connectedness and daily stress.
