Apr 17, 2015. To graph the direct variation #y=5/2x#, determine two points on the line. If #x=0, y=(5/2*0)=0# Point = #(0,0)#. If #x=2, y=(5/cancel 2*cancel 2/1)=5# Point = #(2,5)#. Plot the two points and draw a straight line through the points. graph{y=5/2x [-7.605, 12.395, -3.345, 6.655]}r.
The formula for the index of qualitative variation is: IQV = K(1002 â Î£Pct2) / 1002(K â 1) Where K is the number of categories in the distribution and Î£Pct2 is the sum of all squared percentages in the distribution. There are four steps, then, to calculating the IQV: Construct a percentage distribution.
