Probability and statistical thinking

Calendar of learning activities

This is a tentative schedule that may be changed based on the needs of the students, the needs of the instructor, or any apocalyptic events that may occur during the semester.

Special note: "CA" stands for "Class Activities" as found near the end of the course textbook or scanned into Canvas.

TMTh

Class preparation

Class agenda: How do experiments lead to probability? How can we determine probability without experiments?

  1. discuss class preparation activities
  2. teams need: 2d6 (different colors), d4, d8, Roller derby board
  3. notation for experimental probability,
    P(event) = (# event)/(total # outcomes)
  4. Law of large numbers: as number of trials increase, the closer the experimental probability reflects the actual (theoretical) probability (Excel)
  5. represent sample space for 2d6 using: list (e.g., dice), grid, tree diagram; then compute theoretical probabilities
  6. compute theoretical probabilities for 2d4 using a sample space (hint: P(5) = 1/4)
