13. Chapter 2 - Data * Context of the data is absolutely essential before we do anything! • The W’s (and H): Who, What, When, Where, Why, How • “Who” does not always imply people * Data tables help organize the data * Each row of a data table is called an individual case

14. * Individuals = the things that we want to collect data from. People, animals, cars, etc. * Cases are usually from a SAMPLE of a larger POPULATION (hopefully representative) * POPULATION = ALL individuals that we want to conclude about * SAMPLE = small group of the population that we actually collect data from. Use this data to conclude about the population

15. Read to middle of p. 11 • Variables are the “WHAT” of the data- things that were observed or collected. • Two types of variables: • Categorical: variable that names categories (words or numeric) • Quantitative: variable with numeric values, makes sense to take an average (must have units) - Examples: Colleges/Universities

16. Example: Colleges/Universities Categorical Quantitative Type of major (business/math/etc.) SAT/ACT scores (points) Type of housing (dorm/apt/commuter) tuition cost (\$) Division of sports (DI, DII, DIII) graduation rate (%) Type of university (liberal arts, public, private) number of sports offered Rating of school (4 stars, 3 stars, etc.) teacher/student ratio
