How do you determine independent/dependent variables in Social Research?
Based on your scenario of what people will drill for oil: Your independent variable will be, for example: their age, level of education, political stance, etc. like the items you named Your dependent variable will be whether that certain type of person will or will not drill oil. If this were a real experiment, you will manipulate your independent variables (age, education, etc.) to observe the dependent variable (drill for oil or not).
