Distance in miles is aquantitativevariablebecause it takes on numerical values with meaningful magnitudes and equal intervals. A survey asks On which continent were you born? This is acategoricalvariablebecause the different continents represent categories without a meaningful order of magnitudes. Quantitative data can be classified in different ways, including categorical data that contain categories or groups (like countries), discrete data that can be counted in whole numbers (like the number of students in a class), and continuous data that is a value in a range (like height or temperature). A survey designed for online instructors asks, "How many online courses have you taught?" According to a report, today, at least2.5 quintillion bytes of data are produced per day.
