Suppose you were to make a scatterplot of adult daughters' heights versus mothers' heights by collecting data on both variables from several of your female friends. You would now like to predict how tall your infant niece will be when she grows up. How would you use your scatterplot to help you make this prediction?
What other variables, aside from her mother's height, might be useful for improving your prediction? How could you use these variables in conjunction with the mother's height?
