Lesson 10-4 Misleading Graphs and Statistics Obj: The student will be able to 1) Recognize misleading graphs 2) Recognize misleading statistics HWK: Vocab: 1) random sample

Ex 1) The graph shows the size of tomatoes on plants that were treated with different fertilizers a)Explain why the graph is misleading. b)What might someone believe because of the graph? c) Who might want to use the graph? d) How can you change the graph to make it not misleading?

Ex 2) The graph shows the average price of gasoline in the U.S. in September. a)Explain why the graph is misleading. b)What might people be influenced to believe by this graph? c) Who might use this graph?

Ex 3) The graph shows what percent of the total votes were received by three candidates for student counsel president. a)Explain why the graph is misleading. b)What might people be influenced to believe by the graph? c) Who might use this graph?

Ex 4) a) A researcher surveys people leaving a basketball game about what they like to watch on TV. Explain why the following statement is misleading “80% of people like to watch sports on TV.” b) A researcher asks 4 people if they have seasonal allergies. Three people respond yes. Explain why the following statement is misleading “75% of people have seasonal allergies.”
