Storyboard Text

  • Hey John, remember the project for history class?
  • Yes, I do. The research project about who prefer chocolate flavor ice cream right?
  • Do you want to create a survey where the population will be based on the number of people in our grade?
  • Oh yeah! That sounds like a great idea! And the sample will be the people who like chocolate flavor icecream. 
  • Oh Yeah, the only primary data we have to find out on our own is how many students in them prefer chocolate flavor ice cream. But how we are going to do this?Their are so many students in our grade!
  • Base on the secondary data from our teacher, we know that there are 100 people in our grade
  • I have my own way to collect those data, come!
  • Really? wait!!!
  • And use that information to estimate the population as a whole? Right! That sounds like a great idea! And it's going to be so much easier!
  • Do you know what is Inferential Statistics? We can randomly choose 20 students in our grade, and make a survey about what flavor of ice cream they like.
  • Well, I think in able for us to make a survey we should first state our purpose at the beginning. And I also think we shouldn't ask a bias question
  • How are we going to make the survey?
