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

  • Average score over all enrolled students = 73.8
  • Median score over all enrolled students = 73
  • Standard deviation is around 12 points = 15.1

The distribution is shown below.



Breaking down the performance, the average scoring and confidence intervals are shown below (scaling STDEV = 0.25).

Insights per question:

  • Most common error was the application of the similarity metric in k-Means
  • Itemset questions had the highest average scoring and lowest standard deviations
  • The most difficult question was the final probability question
