  4. Data The data that is necessary to make the graph is the total number of the certain subject and the total number for each sector in order to find the percentages for the graph.

  5. Explanation Step 1: Collect data from students in Honors Algebra Step 2: Put data into Microsoft Excel and create a pie graph with the percentages Step 3: Transfer pie graph from excel onto the PowerPoint document Step 4: Label each section correctly with each category

  6. Problem If ten more students came into the class how many would you expect to play at least three sports in a year?

  7. Advantages Advantage 1: You can visually see how many sports are played in a year by the students of Honors Algebra. Advantage 2: Easy to compare each section with one another.

  8. Disadvantages Disadvantage 1: Not easy to compare with other types of data. Disadvantage 2: Does not work with all types of data. Ex: y=2x+4
