Data Tables zA data table has three titles. zIndependent variable (IV) is on the left side of the data table. zDependent variable (DV) is on the right side of the data table. zData arranged in rows and columns. Average Daily Temperature for January 1-5 in Degrees Fahrenheit DateTemperature (°F)

Graphing

Overview

All graphs start here! zDraw and label both axes. x y 0

Variables z x- axis : Independent variable z y- axis : Dependent variable DVTitle IV Title x y 0

All graphs have THREE TITLES!

Titles z 3 labels per graph: - Main title that describes the graph - x-axis - y-axis z The titles come from the data table.

Investigation 5 z Make a title for your graph. Number of Each Type of Car x y 0 Cars in the Teachers’ Parking Lot

Bar or Line????? Bar Graphs zused for descriptive or grouping information (compares data) zExamples: 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.

Quick Review

Range z From lowest to highest.

Bar - y axis zNumber the y-axis only! zUse an increment small enough to cover entire graphing space but large enough to include highest number. Cars in the Teachers’ Parking Lot

Bar - x axis zWrite the groups (words) from the left side of the data table Cars in the Teachers’ Parking Lot Chevy Dodge Ford Honda Mazda Toyota Volvo

Bar Graph zDraw the bars. Cars in the Teachers’ Parking Lot Chevy Dodge Ford Honda Mazda Toyota Volvo

Quick Review

Increments zThe numbers on the axis. - Line graph: x and y axis=range zEqual to multiples large enough to include highest number. (ex: 5, 10, 15, 20 or 100, 200, 300, 400 or 1, 2, 3, 4……)

Line - y axis zNumber the y-axis! zUse an increment small enough to cover entire graphing space but large enough to include highest number. Scores on a Science Test

Line- x axis zNumber the x-axis! zUse an increment small enough to cover entire graphing space but large enough to include highest number. Scores on a Science Test

Ordered Pairs z Two numbers that join together to make a point on a graph. ( x, y) (2, 3)
