Describe linear relationship
WebThe relationship between x and y is called a linear relationship because the points so plotted all lie on a single straight line. The number 9 5 in the equation y = 9 5 x + 32 is the slope of the line, and measures its steepness. WebThe correlation measures only the strength of a linear relationship between two variables. It ignores any other type of relationship, no matter how strong it is. For example, consider the relationship between the average fuel usage of driving a fixed distance in a car and the speed at which the car drives: The data have a smooth curvilinear form.

WebVariables that give a straight line with a constant slope are said to have a linear relationship. In this case, however, the relationship is nonlinear. The slope changes all along the curve. In this case the slope becomes steeper as we move downward to the right along the curve, as shown by the two tangent lines that have been drawn. WebFigure 21.12 Graphs Without Numbers.
