Study Notes
Types of Variables
- Variables are characteristics of individuals about which we collect information
- Variables can be divided into two categories: qualitative and quantitative
Qualitative Variables
- Qualitative variables are categorical variables
- Examples of qualitative variables: person's gender, color of a car
- Qualitative variables can be further divided into ordinal and nominal
- Ordinal qualitative variables have a natural order (e.g., letter grades)
- Nominal qualitative variables do not have a natural order (e.g., state of residence, gender)
Quantitative Variables
- Quantitative variables are numerical variables
- Examples of quantitative variables: mileage of a car, person's age
- Quantitative variables can be divided into discrete and continuous
- Discrete quantitative variables have whole numbers (e.g., age of a person on their birthday, number of siblings a person has)
- Continuous quantitative variables have all numbers, including decimals and fractions (e.g., height of a person, distance a person commutes to work)
