    Underrated channel, I learned more in 7 minutes than the hours of statistic lessons I got in school. Some terms weren't explained clearly, so thanks to this video, I can finally understand it.

    OMG! The tip that the value from the standard normal distribution table = the area to the left (regardless of the z-score being positive or negative) was everything. Totally unlocked the mystery! Thanks!!

    Although this video is 4yrs old, its helped me sm! thank you "Dude" for going in depth in this video. I'm a freshman in college and my prof. teaches by the book so the examples and the process of answering the question is hard to understand. Thanks to this video, Im confident for my test tmr!

    I can't thank you enough. I have been very confused about this topic in my Stats course and I have tried really hard to understand the material, however, there are still things that I just don't understand. Your video helped me to fill in the knowledge gap I initially had.

  • @Smithsisters-tc2bu
    @Smithsisters-tc2bu 4 ปีที่แล้ว

    if both the values are to the right of the mean do the values for area work the same but opposite. Meaning the area values account for the amount of area to the right of your data value.

    • @Smithsisters-tc2bu
      @Smithsisters-tc2bu 4 ปีที่แล้ว

      rather than the left as shown in the video

    • @whatsupdude2778
      @whatsupdude2778  4 ปีที่แล้ว +1

      If I understand your question correctly then yes, the right and left sides are a mirror image of one another. For instance, the Z value of -1.8 has an area of .0359 to the left of it, the opposite Z value of positive 1.8 does have the same area of 0.359 to the right of it. Hope than answers your question.
