In a regression line y a + bx x is
WebApr 12, 2024 · Linear regression is a way to model the relationship between two variables. You might also recognize the equation as the slope formula. The equation has the form Y= a + bX, where Y is the dependent variable (that’s the variable that goes on the Y-axis), X is the independent variable (i.e. it is plotted on the X-axis), b is the slope of the ... WebWhen r is negative, one variable goes high as the other goes down. Linear regression finds the best line that predicts y from x, but Correlation does not fit a line. Correlation is used when you measure both variables, while linear regression is mostly applied when x is a variable that is manipulated.
