Midterms are graded and will be returned the week after next (March 21). The statisics are as follows:

  • Average score over all enrolled students = 63
  • Median score over all enrolled students = 65
  • Standard deviation is = 13.4

The distribution is shown below.

Insights per question:

  • Questions 2 (Lone Wolves and Influencers) and 10 (KBB, Bayes Theory) were the most difficult
  • Question 5 (Maximum Likelihlood) had the most amount of variance
  • Question 7 and 8 (Association Rules) People appear to generally understand frequent itemsets
