|dw:1362455166347:dw| well it's not quite exact but it's a rough sketch

kirbykirby · Answer

correlation is positive if the slope is positive
it's negative if the slope is negative
no correlation means that there is no LINEAR relationship between the two variables (by linear, I mean it fits a relationship if the point "form a line")

kirbykirby · Answer

this website kind of gives a good idea about correlation: http://www.mathsisfun.com/data/correlation.html

kirbykirby · Answer

so the points line up quite well right :) so it would be a positive correlation, since both variables x and y increase together (forming a positive slope)
