Correlations of scatter plots
WebAlso called: scatter plot, X-Y graph. The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a … WebA positive association is when the line on the graph is moving upward, like in Problem 1. You see, the line is moving up. Therefore, it is a positive association. In Problem 2, the line is moving down. That is called a negative association. No association is like in Problem 3, when there isn't a clear line at all. I hope this helps!
