    This series has helped my more in 30 mintues than 3 different lecturers did over 20+ hours of lectures, you have an incredible ability to explain things simply without being reductive and waste no time without feeling rushed.

  • @shankhariswaminathan7477
    @shankhariswaminathan7477 4 ปีที่แล้ว +1

    Sir, I have a doubt. Why do we need r-square to tell us how well the regression line fits the actual data, when we get the same aspect served by the absolute value of r itself? An absolute value of r closer to 1 indicates that the regression line is a good fit.

    • @Simplelearningpro
      @Simplelearningpro  4 ปีที่แล้ว +2

      Yes that is correct, an absolute value of r equal to 1 indicates that an r-squared value would also be equal to 1. That is an instance where it would be pointless to use r-squared to see if the regression line is a good fit. However, we can use r-squared in cases where the answer isn't really clear cut, and is a way for us to "check" when we need more information.
