Dean's 102H Statistics class: Spring 2003

I made up a handout (.ps) to help guide you for the final. You can get the answers to the Freedman problems from outside my door. The answers to the MLE questions are: (I did these in my head--so I'm not positive they are correct. If you disagree, send me an email.)

• n/sum(log(x))
• (n/sum log(x))^2
• squareroot(sum(x^2)/2n)

General information:

• Results of the first midterm:
  • Oops: question 13 should be d not e on the key
  • I'm going with 5 points per question.
  • Median = 16. IQR = 15 to 19.
  • Mean = 16.5. SD = 3.0
• Sample midterm (solutions)
• Background for the course: Next year 101H and 102H will be completely rewritten. Next year 101H will cover basic statistics and 102H will cover regression. So if you have already had a course in basic statistics (say AP stat) you would be best served waiting until next year.

  But, if you have had a course in probability, then that is the background I'll be assuming. (For example, 101H covered pure probability this year.) I won't actually use this background till later in the semester. So don't judge the course by what I'll cover in the first few classes. If you don't have a strong probability background, stop by and talk to me to make sure you won't end up drowning.
