If a researcher finds that individuals who report higher levels of education tend to also report higher income levels, what underlying factor could be contributing to this relationship?

When researchers see that people with more education often earn more money, they might think that education leads to better job opportunities. One underlying factor could be the skills and knowledge gained through education, which make individuals more qualified for higher-paying jobs. For example, someone who completes a college degree may have specialized training that allows them to work in fields like engineering or healthcare, which typically pay well. Additionally, education can help people build important connections and networks that can lead to job offers and promotions. So, while education and income are related, the skills and opportunities gained through education might be the real reason for this connection.
