GROUP PROJECTS to be presented the week of October 15th-19th

:

  2. 1 person to make up a handout to give to everyone in the class that outlines key points of the article. NOTE! the presentation is not just reading off this handout.
  3. 1 person will come up with 5-10 quiz-level questions that could be asked about the material the group is presenting (1 page with just the questions, another with questions and suggested solutions written in complete sentences when reasonable).

      2. calculating mean, median, mode, standard deviation and range of their own data
      3. keep track of:
        1. What kinds of people polled (look for bias in your sample)
        2. Who was polled (so you don't overlap)

    • and the group needs to also:
      1. present a graph of the collective data (can draw it on the board) in class on FRIDAY OCT 12th
      2. include mean, median, mode, stdev, range of the collective data
      3. be able to talk about bias in your samples and what you can conclude about your data
