A somewhat surprising fact about coffee is that the longer it is roasted, the less caffeine it has. Thus an "extra bold" dark roast coffee actually has less caffeine than a light roast coffee. What is the explanatory variable and what is the response variable? The roasting time is the variable. The amount of caffeine is the variable. Do the two variables have a negative association or a positive association?
