Graphing Skills small medium large Graphing Notes: You will need to come by my room to copy the graphics. Data Table is a way to organize data in columns so it is neat and readable. Title is a brief way to describe the content of a book, graph, or data table. Variable is a word used in a data table to describe what information is being collected. Unit is a word or symbol; used in a data table that tells how the information was measured. A data table includes variable and units. A variable describes what information you are recording. A unit tells how you are going to measure that variable. VARIABLE (UNIT)-WHAT (HOW) Ordered pairs are two pieces of data directly corresponding to one another. A Complete Data Table must meet the following guidelines: 1. a descriptive title 2. variables describing what information has been collected 3. units telling how those variables were measured 4. data collected in ordered pairs 5. all work done neatly Graph is a picture of information in as data table; a graph is a picture of a data table. Why-because it has the same descriptive title, the same variables and units and the same data. The horizontal axis is the axis that goes across the bottom of the graph. The vertical is the axis that runs up and down on the side of a graph Intersection is the crossing of two lines when graphing Data Point is the place where the twp data lines cross (or intersect) Plotting is the finding of data points for an ordered pair. To read a graph you find the data point. Locating the data point by finding the intersection of the two lines is called plotting. An interval is an even spacing of the number along the axis of the graph. You will most always satisfy your needs if you label the axis in intervals 5, 10, or 100. The inconsistent variable is located on the vertical and the consistent variable is located on the horizontal axis. Line Graph Guidelines Materials: Graph paper, ruler pencil for data points only. 1. Always use graph paper. 2. Draw lines with a ruler. 3. When drawing the horizontal and vertical count three to four quads. Horizontal from the bottom and vertical from the left to right. 4. Do all graphs in black ink. 5. A complete graph has a descriptive title, both axes k labeled correctly, data points plotted neatly, and a line connecting data points drawn with a ruler. 6. Use the whole piece of paper. T-data table L-graph Or, would you like to view and optionally restore one of these previous versions? Password: Forgot your password?
