Christmas Survey • What is the most popular gift this Christmas? • Each student will chose one of the following: • Video Game (Call of Duty: Ghosts) • Clothes (gift certificate to Aeroposatle) • DVD (Hunger Games, Fast & Furious 6, or Despicable Me 2) • We will collect information about the class. • Each of you will ask 9 people (plus yourself), then calculate the number of students who gave each answer as a fraction, decimal, and percent. • Write down the names of the people that you talked to.

  6. Results • What was the class average? • How close was your result? • It should have been within about 15% • If your result was really different from the class average, why do you think that was? • If your result was really similar, why do you think you got it right?
