NettetIt 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 ¯). Nettet1. okt. 2024 · Simple Linear Regression (SLR) does just that. It uses this old school formula of the straight line that we all learned in school. Here is the formula: y = c + mx Here, y is the dependent variable, x is the independent variable, m is the slope and c is the intercept In the graph above, the exam Score is the ‘y’ and the Hours of Study is the ‘x’. braided hair for men
