Bivariate data and scatter plots ppt
WebIf you are not satisfied with simple scatter plots you might want to add the frequencies of the data points at each value of the discrete variable. How to do this then just depends on the statistical program you are using. Here is an example for Stata. You can also apply this to the scatter plot of two categorical variables. WebThe notes are created in a "doodle note" format for students to create a quick visual reference page to study for topics in Unit 6. Feel free to write in your own words/notes/phrases -- however, I did include an answer key for how I filled in with my students. Topics include: Scatter Plots, Trend Lines and Two Way tables.
