- - - - if not easily understand --> do minimal training
    - - A --> B 5 times B--> A 5 times
    - - count the number of correct response and compare to table (one-sided or two-sided)
      - Table T 10
        
        (p= 0.01) --> No.12 --> minimum 11 say A is better --> samples are sign diff
- - - - recommend to chech whether sick or not --> mistakes
    - - 2 samples : t-test // more than 2 : ANOVA
  - - - constant reference
        
        the same sample is always the ref.
      - balanced reference
        
        both samples are randomly used as ref.
    - - one sided b/c know that A is identcal
      - n=40, p= 0.05 --> min= 26
  - - - table T8
      - n=15, p=0.05
        
        minimum = 9
        
        people can identify the odd sample at least 9times = sign diff
