Slope and y-intercept of a Regression Line (Best Fit Line) Calculator
WebJan 20, 2024 · Your answer will be correct as long as your line of regression nicely follows the sample data according to the observed correlation and your calculations are correct for the two sample points you choose, as Math Bits nicely states. Otherwise, if you want an accurate line of best fit, you will need to use a graphing calculator or computer. WebIf there is only one explanatory variable, it is called simple linear regression, the formula of a simple regression is y = ax + b, also called the line of best fit of dataset x and dataset y. For Linear Equation: y = ax + b, formula to calculate the a and b is: Where: x: mean of x. y: mean of y. xi: the ith number of x. yi: the ith number of y. WebYou can use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. It also produces the scatter plot with the line of best fit. Enter all known values of X and Y into the form below and click the "Calculate" button to calculate the linear regression equation. 北川工業 ワイヤーサドル
