Comparisons, Benchmarks, and Confounding Factors

(bit.ly/dsia06f} Part F of Lec 6 explains that comparisons require benchmarks. It is important that the benchmarks should be “comparable” in the right way with the cases under evaluation.

Quartiles as Natural Data Summaries

[bit.ly/dsia06b] Part B of Lec 6 on Descriptive Statistics: An Islamic Approach. The basis of REAL statistics is the actual data distribution. This contrasts with Fisherian Statistics, which makes a hypothetical imaginary theoretical distribution the center of investigation. Natural summary statistics for the actual data distribution are the quartiles. What these are and how they …
