    Formula

  • Regression Equation Y = a + bx
  • Slope b = (NΣXY - (ΣX)(ΣY)) / (NΣX2 - (ΣX)2)
  • Intercept a = (ΣY - b(ΣX)) / N
  •  
  • a = The intercept point of the regression line and the y axis
  • b = The slope of the regression line
  • X and Y are the variables
  • N = Number of values or elements
