Business Drivers
The correlation between two variables is the degree to which the variables move in the same direction. A positive correlation means that the variables both move in the same direction, and if they are correlated that a movement in one will result in a movement by the other. . For example, the number of students who need school lunches and the funding that the school receives for lunches will have a positive correlation. This is because the funding formula is based on how many students need lunches. There is basically a variable cost element to that, where each student is worth x amount of money, so every student that needs a school lunch increases the funding that is made available to the school to provide that lunch.
A negative correlation means that as one variable moves up, the other variables goes in the opposite direction. For example, the age of the student when the subsidy is received will be negatively correlated with the impact of the subsidy. The reason for this is that the subsidy for school lunch will have a greater impact on younger students. Those younger students are in a position where a school lunch affects...
