09 – Regression Analysis


Regression Analysis 1

  • If two variables are correlated, you can create an equation that will predict one of the variables if the other is known.
  • This equation is known as a regression analysis because it estimates the point that a score will fall on a regression line.
  • Regression analysis assumes that there is a relationship between two variables and that this relationship can be represented as a straight line.
  • Therefore if we know where X falls on this line, we can use the regression equation to predict where Y could fall on this same line.
