Types of Variables

◮ Qualitative

◮ Ordered (e.g., modem, Ethernet, satellite) ◮ Unordered (e.g., CS, math, literature)

◮ Quantitative

◮ Discrete (e.g., number of terminals) ◮ Continuous (e.g., time) 4 / 25

Types of Variables

Charting Based on Variable Types

◮ Qualitative variables usually work best with bar charts or

Kiviat graphs

◮ If ordered, use bar charts to show order

◮ Quantitative variables work well in X-Y graphs

◮ Use points if discrete, lines if continuous ◮ Bar charts sometimes work well for discrete 5 / 25
