GRAPH • A graph is a visual display of data and can help to reveal a pattern in data, if one exists. There are different types of graphs, including circle graphs, bar graphs, and line graphs

Circle Graphs • Sometimes called a pie chart • The whole circle represents 100% – Which means data is recorded in percentages – All “pieces” must add up to 100% – Create a circle graph on your handout dividing your free time up into your hobbies or afterschool activities. Make sure the total is 100% – Add a title – Label each percentage – Label each “pie piece”

Bar Graph • Often used to show a quantity varies with different factors • Create a bar graph using your quarter 1, quarter 2, and quarter 3 grade so far. – You should have 3 bars and give your graph a title – Label your Y axis and X axis appropriately – Make a 4 th bar for the grade you would like to earn for 4 th quarter

Line graphs • The points on the line graph represent the intersection of data for two variables • Sometimes the data is scattered and a line cannot be drawn through all points – Use a best fit line • Create a line graph of height and shoe size for the class
