Visualizing categories

We've added other categories to the data: Toys/Hobbies and Collectibles.

Notice that this Category column has no numeric information. This is because they are attributes of the auctions. They are distinct classes or factors. You can learn a lot about your sample descriptive statistics by better exploring these factors. For example, in patient data, gender could impact the average weight. Understanding if you have more "Females" would help you understand if the weight is possibly impacted.

In this new auction sample, closing price averages have been compared across categories. Are categories impacting this descriptive statistic? Time to find out!
