Document Summary
Regression analysis: a way to express the relationship between two or more interval-ratio variables. Bivariate regression: refers to regression of a dependent variable on one independent variable. Multiple regression: refers to regression of a dependent variable on multiple independent variables. Are a quick first step in trying to determine whether there is some meaningful pattern in the plots (cases) on the diagram. Like our other graphs, a scatter plot has an x and y axis. Each observation has both an x and y axis. Are a quick first step in trying to determine whether there. Its not always easy to decide just what exactly is going on. Want to express the relationship between dependent and independent is linearly. The line that runs through a scatterplot is a summary of the way the points are distributed across the graph. This means that how steep it is reflects how points are scattered.
