Today, we continued our discussion on measures of location, percentiles, and started measures of variation. Specifically, we saw Range, Interquartile Range (IQR), Variance and Standard Deviation. We discussed limiations of the range, and IQR, and started discussing Variance.
Based on suggestions from you, I will try and include more examples like the Quiz in my lectures. Please come prepared on Thursday with any doubts, questions for Exam 1. I felt that the Section 002 lectures went much better than Section 001 for various reasons including audio issues. I would suggest that if you are reviewing the lectures, try Section 002 first, even if you are in Section 001.
Section 001
