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!!
I don't do statistics as a major but it's a requirement in Medical Laboratory Sciences to understand quality control. Thanks for the video. 😎it was direct, straight and simple to follow.
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.
You are great !! A BIG THANK YOU. Now I really understand how to use the Table z. All this while, I am blank. Thank again. You are awesome. In future, perhaps you can slow down the speed. Your video is superb. I get a better understanding on this topic.
What if the question is like this. Find the area below M? or like find the area bet. M & positive 1? Do you have to use the normal distribution table or not?
I don’t understand why you went 5 over when finding the number on the Z Chart and not 4… please explain better and in more detail because you are the 8th video I have watched and all of you leave out important information… details, please explain
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.
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.
@@LeMap-d2n I'm sorry I did end up getting an A in the test and my stats class but I don't remember how I understood that and I'm high rn :/ I'll give it another look when the edible wears off
