Post subject:  + and  correlation 
Would someone be willing to explain to me the difference between positive and negative correlation. I understood it in class but now that i am working on the final i can't seem to wrap my brain around the idea. Thanks so much!!

If I understand it correctly, an example of positive correlation can be observed between class attendance and grades. As a student attends class more often, their grades are more likely to go up and as a student misses classes, their grades are more likely to go down (both variables move in the same direction with positive correlation). I can't think of a good example for negative correlation right now but with a negative correlation the variables move in opposite directions. So as x occurs more often y will occur less often, and vice versa.

An example of negative correlation is grades and number of absences. When the number of absences is high, grades are low, and vice versa.

Imagine a graph. A postive slope is one taht goes up from left to right, meaning that both axises [sic] are low, then as it gets higher, both axises are high. So if the Y axis is Grades, and the X axis is Attendance, then it would be a postivie slope, correlation. As attendance goes up so does the grades. negative would be a negative slope.
