**Qualitative Variables**: **categorical**, have 2 or more categories with no intrinsic ordering (male and female; hair color, states), *you can assign categories but can’t clearly order the variables*

**Quantitative Variables**: **ordinal** or **interval**, have a clear order (low, med, high; elementary school, high school, some college; agree, strongly agree, neutral) or clear order of *equal* interval (income of $10,000, $15,000, $20,000; years of education), *you can assign categories which contain intervals distances, ***discrete** or **continuous**, numeric values that are finite integers (number of people) or numeric values that are infinite ranges (weight)
