Final answer:
A strong negative correlation indicates that as emotional instability increases, income decreases, suggesting that emotional factors can significantly influence economic outcomes such as job performance and earnings.
Step-by-step explanation:
Mildred finds a strong negative correlation between how emotionally unstable someone is and how much money they make. This means that the more emotionally unstable a person tends to be, the less money they make. The term 'negative correlation' in this context implies that as the level of emotional instability increases, the level of income decreases.
This can be seen in various aspects of life where, for instance, emotional instability may affect someone's ability to maintain steady employment or perform well in their job, which in turn affects their income. It is essential to understand this relationship as it reflects on how psychological factors can have practical implications on economic outcomes, such as the income effect of higher wages allowing for more leisure as indicated by Petunia's preferences, or how behavioral economists like Kahneman and Tversky explain the loss aversion which affects financial decisions and thus potential earnings.
