Title: Data scraping, ingestation, and modeling: bringing data from
cars.com into the
intro stats class
Abstract: In this webinar, I will describe a classroom activity where pairs of students
hand scrape data from
cars.com, ingest these data into R, then carry out analyses of the
relationships between price, mileage, and model year for a selected type of car. This
early in the semester activity can help illustrate the statistical problem solving
process. The "Less Volume, More Creativity" approach utilized by the mosaic
package facilites the analysis with a minimal amount of syntax. Key concepts that are
introduced and reinforced including data ingestation, multivariate thinking through
graphical visualizations, and regression modeling. Extensions and additional use of the
dataset will be discussed along with potential pitfalls.
