Graphing+Information+and+Analysis


 * __ Graphical Information __**
 * When creating a graph make sure to have the following:**
 * Title
 * Independent Variable on the X axis (usually time)
 * Dependent Variable on Y axis
 * Units labled on both axis
 * Key

The purpose of a graph is to analyze results of a comparison between two variables and communicate the difference in an effective manner. There are many different types of graphs such as line graphs, bar graphs, and picture graphs.
 * Summary:**


 * Line Graphs show the change in variables over time. It should be clear by looking at the graph that each point corresponds to both a particular measurement of a substance and time. The slope in the line graph is the change in one variable and how it compares to the change in the other variable. Depending on the variables and the change, the slope can either be extremely steep or flat. A completely horizontal or vertical line has no change. A line graph can be drawn with broken lines.
 * Picture Graphs show information quickly and simply and are often used in newspapers.
 * Bar Graphs show the amounts of different variables.
 * Vocab:**

**Extrapolation:** The broken line portion of the graph **Interpolation: ** To estimate the value of a function between two points **Independent Variable:** (X-axis) a manipulated variable; a factor or condition that changes naturally or is intentionally manipulated by the investigator to observe the effect **Control:** A standard against which other conditions can be compared in a scientific experiment **Axes:** Scales that are carefully marked with number, labels and units **Index Marks:** Scale marks on the graph **Frame:** Square drawn around the whole graph, with index marks placed all around **Ordinate:** Vertical axis of a graph ** <span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Rate-Temperature Graph: **<span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Shows the relationship between temperature and the rate of a something. ** <span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Time-Rate Curves: **<span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Graphs that have time on the abscissa. This can be made from any progress curve. ** <span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Abscissa: **<span style="font-family: 'Arial','sans-serif'; font-size: 10pt;"> The value of a coordinate on the horizontal axis ** <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 10pt;">Slope: **<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 10pt;">Measurement of the speed or velocity, or rate of the reaction. ** <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 10pt;">Rate: **<span style="color: black; font-family: 'Arial','sans-serif'; font-size: 10pt;">A magnitude or frequency relative to a time unit. A ratio between two measurements, often with different units
