If the correlation is positive: as x increases so does y, as x decreases so does y, the line goes from bottom left to top right. If the correlation is negative: as x increases y decreases, as x decreases y increases, the line goes from top left to bottom right. If the correlation value is +1 or -1: there is a perfect correlation between x and. If the correlation is 0: then there is no relationship between x and y, correlational research aims to. Experimental methods: aims to establish causation by controlling environment.
