    I think that watching your videos can give a lot of people more...faith that they will do well on their tests. 😎
    But in all seriousness, I love Khan Academy!

    This was a good video, but how can I calculate the standard deviation for a regression? Or calculate SE for a regression coefficient? Is that the same as standard error of estimate?

    Good explanation, where as my study book just provides the final answer instead of the calculation. THX!

    shouldn't the caffeine intake be in axis Y and time studying in axis X?

    • @QueenOfMettall
      @QueenOfMettall 3 года назад +3

      no because time of studying depends on caffeine intake not vice versa (y depends on x)

      @@theforester_ I mean yes you could also look at if students drink more coffee the more they study, it depends on how you phrase the question and what you are looking for :)

    5:14 Why can't we use z statistic instead of t statistic?

      IDk. Also, my friend opened up 4 tabs of a maths Khan Academy video, and played them all at the same time.
      Believe me, it sounded like something very, annoying.
      I just did it for no reason :P

    Doesn't the confidence interval vary depending on what the x values are. I don't think it is a constant value away from the line of best fit

    I am super lost. It's been YEARS since I took a math class and I need to know how to investigate the uncertainty of an allometric equation. Can anyone help me or direct me to material that will give me a better understanding about how to do this?
