1. Graphing • Data: Information • Data Table: a way to organize data in columns so it is neat and readable • Title: a brief way to describe the content of a book, graph or data table • Variable: a word used in a data table to describe information being collected • Unit: a word or symbol used in a data table that tells how the information was measured • Ordered pair: two pieces of data directly corresponding to one another

2. Graphing, cont. • Graph: a picture of information in a data table • Horizontal axis: the axis that goes across the bottom of the graph • Vertical axis: the axis that runs up and down on the side of the graph • Intersection: the crossing of two lines when graphing • Data point: the place where the two data lines cross (or intersect)

3. Graphing, cont. • Independent variable: the factor that you change • Dependent variable: a measurable result or response

4. A properly constructed graph follows these guidelines: • Descriptive title • Both axes labeled correctly • Appropriate intervals • Data points plotted neatly • Line connecting data points drawn with a ruler • Use the whole page of graph paper!

5. A properly constructed data table follows these guidelines: • A descriptive title • Variables describing what information has been collected • Units telling how those variables were measured • Data collected in order pairs
