Regression analysis relates an dependent variable to an independent variable. The relationship between the two can often be represented by a straight line on a scatter plot called the least squares line or linear regression line. This line can then be used to make predictions. Think of (or find through research), a situation where two variables might be related. Identify which is the independent (explanatory) variable and which is the dependent (response) variable. Do you think there would be a strong, moderate or weak correlation between the two? What predictions could your linear regression line make?
