WebSample conclusion: Investigating the relationship between armspan and height, we find a large positive correlation (r=.95), indicating a strong positive linear relationship between the two variables.We calculated the equation for the line of best fit as Armspan=-1.27+1.01(Height).This indicates that for a person who is zero inches tall, their predicted … WebIn the simple regression case, we evaluate the overall fit as the sum of squared errors, the smaller the better: SSE = ∑ni = 1(yi − ˆyi)2 = ∑ni = 1(yi − (a ⋅ xi + b))2. So the “best fitting” line is the line with a slope ( a) and intercept ( b) that yields the smallest sum of …
