Regression Formula - Correlation And Regression

Regression Formula :

Regression Equation(y) = a + mx
Slope(m) = (N x ΣXY - (ΣXm)(ΣYm)) / (N x ΣX2 - (ΣX)2)
Intercept(a) = (ΣYm - b(ΣXm))


x and y are the variables.
m = The slope of the regression line
a = The intercept point of the regression line and the y axis.
N = Number of values or elements
X = First Data Set
Y = Second Data Set
ΣXY = Sum of the Product of First and Second Data Set
ΣXm = Mean of First (X) Data Set
ΣYm = Sum of Second (Y) Data Set
ΣX2 = Sum of Square of First (X) Data Set Values
