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

Individuals = the things that we want to collect data from * 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

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

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
