Question: 1. State the equation of the regression line used to predict values of the criterion variable.
2. Distinguish between the predictor variable and the criterion variable.
3. What method is used to determine the equation of the regression line for a set of data points?
4. Explain why it is necessary to square the deviation of each data point from the regression line to compute the method of least squares.
5. Define the following terms: (a) Slope (b) y-intercept
6. State three steps used to compute the method of least squares.
