A Teaching Topic in Quantitative Methods
This topic teaches students an important statistical technique that is used to measure or quantify the relationship between two and only two variables. This technique is called simple regression, or bivariate regression. Regression models that have more than one independent variable are examples of multivariate regression analysis, which is usually taught as a separate topic. Regression models are important for public policy because they can be used to test theories, make predictions and test hypothesis about relationships between variables.
Topic Learning Outcome: Students will be able to clearly define simple regression and be able to calculate the level of correlation between two variables using software such as STATA, SPSS or Microsoft EXCEL.
Core Concepts associated with this Topic: Influential Observations; Ordinary Least Squares Estimator; Regression Analysis; Regression Line.
