Strong vs weak association scatter plot

WebThe strength of a scatter plot is usually described as weak, moderate or strong. The more spread out the points are, the weaker the relationship. If the points are clearly clustered, or closely follow a curve or line, the relationship is described as strong. The linearity of scatter plot indicates how close the points are to a straight line.
