    Sir , in the second question 1st and 2nd judge both values are in negative then why are 1st and 3rd judges rank similar !??? Kindly explain this , I am unable to get this. Thank you.

    • @abhimat31
      @abhimat31 4 роки тому +3

      Because negative value indicates that the 2 judges approach is going in different directions.. ie. When one gives higher marks then second gives lower. That is the relation. Negative relation.
      If you still don't understand then go through the concept of negative correlation and positive correlation under types of correlation.
      Then you will understand. Best of luck.

    • @samratpodder545
      @samratpodder545 4 роки тому +11

      You are considering Pxy as 1st Judge, Pyz as 2nd Judge, Pzx as 3rd Judge. But x,y,z are 1st,2nd,3rd Judge respectively.Pxy is relation between the decision of x and y. Pyz is the relation between the decision of y and z. Pzx is the relation between the decision of z and x. As Pzx has a positive correlation therefore Judge x and Judge y will have the nearest approach to common test of beauty as their Decision move in a similar direction.
