Fundamentals of Statistics 1: Basic Concepts :: Quantitative and Categorical Data
As you'd probably guess, statistics involve using numbers from data. Not all data are the same and knowing what type of data we're dealing with will guide us through what we can do with it. The two basic divisions of data are qualitative or categorical data and quantitative or numeric data.
For example, typing speed is quantitative. Favorite colors are qualitative/categorical. Some more examples are :
Quantitative:
Weight in pounds
Length in inches
Time in seconds
Number of questions correct on a quiz
Categorical
Model of car
Gender
Yes or No
Pass or Fail
Just because you have a number, doesn't necessarily make it quantitative. For example, zip codes, phone numbers and bankaccounts are numeric, but it doesn't make much sense to find the average phone number or median zipcode. These are examples of numbers applied to categorical data.

I apologize for my previous comment. When I scrolled up to look over the screen one last time, I realized that I was mistaken. I looked over the examples that you clearly provided. I am so sorry.

I was looking for examples of categorical data but, there were none. It would be a great addition to the webpage if you added some examples of the various data that you display.
