Different types of data displays (pie, bar, line graphs)

1. __Description of Topic__: a) **Line Graphs**: used to track and record changes over short and long periods of time. Line graphs are more effective when trying to notice smaller changes over the same period of time (temperatures in a city for a month, weight changes in a person over a year) b) **Pie Charts**: best used when trying to compare parts of a whole (ingredients in recipe, expenses for a new product) c) **Bar Graphs**: used to compare different things between groups (favorite ice cream flavors among kids, favorite day of the week among students) The goal of this unit is to figure out the best graph to use according to the information given. 2. __Typed List of Rules, Formulas, and Properties:__ a) **Pie Charts**: b) **Line Graphs**: c) **Bar Graphs**: 3. __Examples:__ What is the pattern of weather for the month of January?
 * All data adds up to 100%
 * Pie chart is 360 degrees
 * A pie chart can be divided into sectors with angle measures
 * To find this you use
 * Line Graphs are defined by y=mx+b
 * m= slope
 * To find slope use:
 * b= y-intercept
 * You can use this information to graph lines
 * A bar graph is a graph that uses rectangular bars with lengths proportional to the data
 * They can be graphed vertically or horizontally
 * There are no specific formulas or equations that pertain to bar graphs
 * Line Graph**
