Credit 4 is all about experimental units and treatment conditions. You will learn about causation, control, and variability.
The last Module will look at regression analysis. You will use regression analysis to predict the value of a dependent variable based on an independent variable. Regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.
