Finding Equation Of Regression Line Let S Say You Have Coordinates Of Four Point
Finding Equation of Regression LineLet’s say, you have coordinates of four points: 8 Y4For y1, y2, y3, y4 assign any four positive numbers between 10 and 30.Here are 6 steps you should to complete: Compute x-mean and y- mean . Complete the table below: X y x- < x > y- < y > ( x – < x > ) ( y – < y > ) ( x – < x > ) 22468Find sum of column ( x – < x > ) ( y – < y >). This is SxyFind sum of column ( x – < x > ) 2 this is SxxCalculate b1 = Sxy / Sxx and bo = < y > – b1 < x >Write Equation of Regression line in form: y = bo + b1x
