How does a regression give us the “best fit” line to summarize the relationship between two variables?
What will be an ideal response?
In regression, an equation (y=a+bx) is found in such a way that its graph is a line that minimizes the squared vertical distances between the data points and the line drawn. Regression analysis uses a mathematical procedure that finds the single line that minimizes the squared distances from the line.
