Organizing Data Data can be organized into data tables & graphs Data table CityAverage annual rain Buffalo, NY98.0 cm Chicago, IL91.0 cm Colorado Springs, CO41.2 cm Houston, TX117.0 cm San Diego, CA25.1 cm Tallahassee, FL166.9 cm Tucson, AZ30.5 cm

Types of Graphs Line graph: shows changes that occur to related variables Bar graph: useful for grouping into categories Pie graphs: useful for showing how one part relates to the whole

Line Graphs

Relationships Direct relationship: when one variable goes up, the other goes up OR when one variable goes down, the other variable goes down Direct relationship usually between amount of education & income Indirect relationship: one variable goes up, the other goes down OR one variable goes down, the other goes up Indirect relationship usually between
