A regression line is a statistical tool that depicts the correlation between two variables. Specifically, it is used when variation in one (dependent variable) depends on the change in the value of the other (independent variable).There can be two cases of simple linear regression:. The equation is Y on X, where the value of Y changes …

Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% indicates that the model explains none of the variability of the response data around its mean.
WebOct 6, 2024 · The equation of the line of best fit is y = ax + b. The slope is a = .458 and the y-intercept is b = 1.52. Substituting a = 0.458 and b = 1.52 into the equation y = ax + b gives us the equation of the line of best fit. \[y=0.458 x+1.52\] We can superimpose the plot of the line of best fit on our data set in two easy steps. WebIt turns out that the line of best fit has the equation: y ^ = a + b x. where a = y ¯ − b x ¯ and b = Σ ( x − x ¯) ( y − y ¯) Σ ( x − x ¯) 2. The sample means of the x values and the y values are x ¯ and y ¯, respectively. The best fit line always passes through the point ( x ¯, y ¯).
