    • What does SRCC measure?

      Rank correlation between bivariate data for the population.
    • Hypotheses for SRCC:

      H0: There is no rank association between...
      H1: There is a positive/negative/ a rank association between...
    • TS for SRCC
      TS = SRCC value
    • What must be true for an SRCC?

      • sample must be randomly selected
    • Exam technique for SRCC
      • compare against PMCC
      • understand that value shows rank correlation and not necessariley linear correlation
      • can be combined with other hypothesis tests
    • Why would SRCC be preferable?

      • doesn't require bivariate normal
      • can be used for qualitative data
      • if data is monotonic but not necessarily linear
      • data is already ranked
