    Hi Professor, about data(tea) that you used in the video, did you get from the Rstudio itself or was that your own data ? If that was your own data, can i get it to try the data by myself ? thanks

    Hello :) Is it possibile (or even right) to split the ratings when you have to many combinations? So that a part of the participants rate the first half of all "cards"? Because i guess my RStudio cant handle the NA in every row..... And thank you very much for this video. It was very helpful!

      Hi, Garo995.
      Thanks for watching my youtuble video. The adjusted coefficient , +3.394 can be calculated by the sum of intercept coefficient from regression analysis and the centered coefficients. In summary, +3.394 = +7.43 -2.658-1.1494-0.8586+0.6293.
      Regards, Sangwoo.
