In a research study examining the impact of education level on income, which of the following best describes the dependent variable?

In a research study looking at how education level affects income, the dependent variable is the income level of the participants. This is because the dependent variable is what researchers measure to see if it changes in response to another factor, which in this case is education level. For example, if we find that people with higher degrees earn more money, we are looking at how income (the dependent variable) varies based on their education (the independent variable). So, in simpler terms, the income is what we are trying to understand better based on different levels of education. Therefore, in this study, income is the outcome we are interested in observing.
