1. Create a list of shows/movies that are representative of different taste categories*
2. Obtain ranking of the items in the list from 2 users
3. Use Spearman’s rank correlation coefficient to assess dependence/congruence between the 2 people’s rankings.
* To find shows/movies to include in the measurement instrument, a cluster analysis on a large number of viewer’s viewing habits can be done
