Data Tables Average Daily Temperature for January 1-5 in Degrees Fahrenheit Date Temperature (°F) 1 10 2 25 3 30 4 42 5 23 A data table has three titles. Independent variable (IV) is on the left side of the data table. Dependent variable (DV) is on the right side of the data table. Data arranged in rows and columns. Graphing All graphs start here! Draw and label both y axes. 0 x Variables y x- axis : Independent variable MIX DV Title 0 IV Title y- axis : Dependent x variable DRY All graphs have THREE TITLES! Titles 3 labels per graph: - Main title that describes the graph - x-axis - y-axis The titles come from the data table. Investigation 5 Cars in the Teachers’ Parking Lot y Make a title for your graph. Number of Each 0 Type of Car x Bar or Line????? Bar Graphs used for descriptive or grouping information (compares data) Examples:Type of ---, color, weight, height, shape, amount, etc. Bar or Line????? Line Graphs Used when you collect information over time Examples: hours, days, months, years, decades, seconds, centuries, minutes, weeks, temperature, etc. Range From lowest to highest. Bar - y axis Number the y-axis only! Use an increment How you count and label each axis. Increments must include the range of information.
