BY far the best explanation of SHADING area when given the AREA to find Z-value. TIP: for other people i find it it EASIER for to me UNDERSTAND it like this LESS THAN means shade from LEFT side (corner) to the right side
This video helped me so much, thank you! I have a stats exam this coming Monday and I was struggling to understand this because my professor doesn't communicate the best way. You made it very clear and you are very well spoken! Thanks again
I have wasted so much time looking at other math videos, this hits the ball right out of the park. Thank you so much for sharing your knowledge, and teaching it so well. God bless you!
Why can’t you be my stats teacher!?? I’m an older student going back for my college degree and I have “thinks-she-doesn’t-understand-math-brain” but the way you explain it makes me de-stress and understand!!! Thank you!!!⭐️⭐️⭐️⭐️⭐️ PS I think I just figured out that you kind of ARE my Stats teacher now!
Yes Chara. If the probability you're looking for is not in the table, then choose the probability that is closest to it. It may be a probability slightly greater than the one you're looking for, or perhaps it's slightly less than it. Sometimes, the probability is exactly half way between two probabilities in the table. In that case, you can either choose the larger value, or you could split the difference between the two. Hope that helps!
6:17 *LMAO WHEN YOU'RE IN ART CLASS AND YOU SUCCESSFULLY DREW THIS ONE THING THAT LOOKED TERRIBLE BEFORE OOF AND YOU EVEN PAIR IT WITH A THUMBS-UP LMAO*
3:10 but there isn't any number for probability that corresponds to .025, rather, you got to take a complement of that, which is .975, which is then 1.96 in terms of z score.
Aww 😅 I'm a little disappointed since I was expecting some kind of algorithm that would allow me to compute the corresponding Z score of a given p-value without looking at the Z table. I don't really need a Z table since I could easily find the corresponding p-value with just a few taps on my calculator (which is allowed during my statistics exam) and I was hoping to find a way to work backwards from there.
I wonder why we don't want to get an area which is more than half in 7:48 , sir ? Thank you so much for your videos .. it has been a great help ! :) Bless you ^^
You are wonderful sir. Love your videos and I learnt a lot. Keep posting please. Post some 'finding mew and s.d' please. How about poisson distribution? keep posting sir.
Hi "jackd36". Yes, I do read these comments (good and bad ones). Well, look at the video again, beginning at minute 6:03. I show how to do a very similar problem to what you're asking about. Simply replace my P(z > ?) = 0.2389 with your P(z > ?) = 0.3300. The process is the same. Hope that helps!
William Wallace Let's assume unknown variable as x, question says probability of p(z>x)= 0.2389. but the positive table shows from minus area to plus area(upto +z). As you know the whole area is 1 and we want to find more than +z area, so we deduct the given area(0.2389) from 1.
I have a question: Given that z is a standard normal random variable, find the z for each situation. 5.1) The area to the left of z is 0.2199 5.2) The area to the right of z is 0.6915 Help please Thanks in advance

when a 10 minute video explains something better than your professor did
April Morrison amen
Ikrrr
Not most teachers explain clearly what they are teaching but you really do. Thank you so much for that!
This video helped me so much, thank you! I have a stats exam this coming Monday and I was struggling to understand this because my professor doesn't communicate the best way. You made it very clear and you are very well spoken! Thanks again
I'm still struggling with the ones that are structured like this P(-z0
7 years later and poyersmath' video is still helping us. Thank you sir!
Best explanation ever!!!! wishing my teacher could lecture like you
In one night I learned more than I do in one week in class. Best stat video hands down. Thank you so much. Ready for my test tomorrow.
Amazing! You did what my professor was trying to do for 2 lectures of 3 hours each! Bravo! Thank you so much
this helped me so much! now i feel stupid for making those mistakes on my last test! i will make an easy A on this final now!
thanks!
soo... I know it's been 6 years but, how did you do on your finals?
Thank you! your calmness is very helpful.
Your voice is relaxing and the visuals along with your explanation was amazing! I don't find many videos this good on RUclips!
This made it all soooo much more simple to me.
I was in elementary when you made this video. This video is helping almost ten years later, thank you! *thumbs up
I have wasted so much time looking at other math videos, this hits the ball right out of the park. Thank you so much for sharing your knowledge, and teaching it so well. God bless you!
"oh that's terrible" lol 4:31
قلتلهم ايعود
Army!! Hello and omg I'm struggling. I keep getting numbers off😅 I hate statistics since I was in high school
Actual representation of every math student
Great instructions! Pictures and explanation while working out the calculations are a big help! Thanks for being online
could u do an example using this? finding b P(-b
I been studying this for a week and was not getting it. I watched this video and understood instantly. Thanks for explaining this with such clarity!
Why can’t you be my stats teacher!?? I’m an older student going back for my college degree and I have “thinks-she-doesn’t-understand-math-brain” but the way you explain it makes me de-stress and understand!!! Thank you!!!⭐️⭐️⭐️⭐️⭐️
PS I think I just figured out that you kind of ARE my Stats teacher now!
thank you so much. your style of teaching is super calming and very understanding
Thanks for the video. I'm going crazy with how to define negative or positive z-values but it become simple to me now. Really appreciate.
Man, you are the boss , you teach me much better than my school teacher!
Thank you very much. I had never taken a statistics class on this topic but now its crystal clear
this was super helpful! you taught me what i need to know in like 10 minutes than in my 2 hour lecture :) thanks!!!!!
felt so hopeless until i found this video..its 2 am exams are starting tmmrw and this vid was a lifesaver
why can't all profs be like you!! Thank you so much!
excellent video. clear voice and english. English is my 4th language, I can only understand when is accent free. thank you.
Thanks so much for sharing these videos! I post them to my students to watch as it sometimes helps hearing someone else explain it as well!
awesome explanation have been navigating to different videos but this is so far best explanation !!!
U saved my life thank u sir
a piece of paper cant decide your life or future....so enjoy moments and make memories
Thank you very much, just watched three of your videos and i feel a bit more confident taking my quiz on this tomorrow

Awesome teaching! Saved me from dropping my class!
Thank you so much for making this video! I'm stuck in Stats with a teacher who cannot teach to save her life. Thanks!
You are wonderful!... Just Wonderful!!
wow you make it so much more simpler. thank you!!
sitting on my bed at 3 am as i regret taking that 6 hour nap earlier knowing i have a 9 page homework thankyou for saving me omg
What if I don’t have the table? Can I figure this out someway?
Yeah same doubt
No, you can't figure out the values without the table.
thank you!!! God Bless
Your work is great. All what you need is to improve your logistic facilities; including the camera, board, and the light.
BEST STATS TEACHER EVER!!
simply the best stats teacher!!
great video!!
love you so much OMG
Thank you so much for making these videos! I am also using mymathlab and the triola book in my online class. I really appreciate you and your insight.
This video really helped me, thank you.
Thank you , explained it so easy and broke it down step by step for me. thank you agin
more then a decade later and here i am watching this days before my exam
Thanks for uploading this!
6:17 *LMAO WHEN YOU'RE IN ART CLASS AND YOU SUCCESSFULLY DREW THIS ONE THING THAT LOOKED TERRIBLE BEFORE OOF AND YOU EVEN PAIR IT WITH A THUMBS-UP LMAO*
This help me alot....I am a Master student and my exam of Biostatistic gonna be tomorrow 💙💙💙
this really helped me. thank you so much!
Sir, you are an excellent teacher. This helped me in my PhD studies.
Woah u use this in your PhD😮for what, sorry I’m just curious
@@crochetforfun8730 I used it during my initial course work. Not just this but statistics in general
thank youuuuuu!! bcuz of your videos now i understand very well about this..
That's just so wonderful - thank you so much.
Thank you very much. Very good video.Very simple and clear explanation.
This video just saved my life.... thank you sooo much💖

Thank you so much for your videos .. it has been a great help ! :)
Bless you ^^
So simple and great sir..
It helped me really...
YOU ARE A LIFE SAVER!
I watched a lot vedioes but this is the best between there ❤️😍
One Smooooth Operator! Thank you, Sir.... B
Please show an example of finding the value b such that P(-0.37 < Z < b) = 0.5749?
You are wonderful sir. Love your videos and I learnt a lot. Keep posting please. Post some 'finding mew and s.d' please. How about poisson distribution? keep posting sir.
Really helpful videos please upload videos regarding sampling error, sampling distribution of the mean & sampling distribution of the portion thanks.
That was really helpful thanks a lot 🧡
Thank you sir you saved my life

I just found out you can find it by invNorm(AREA, u, sd) now on the TI-Nspire
This saved me so much time, you are a god
I had a comment but i took it back...sorry.
actually,your video is a big help!
Thank you!
I apologize!
You are amazing.
Nice video. Thank you.
Thank you very much for the video.
+poysermath
7:52 is wrong, you have an extra one??? Please explain why this is right because I am confused now...

Is there any way to figure out how many standard deviations from a z value?
Very clear! Thank you!
Thanks. This saved me.
Amazing, that cleared up so much, thank you!
*Throws tuition
omg your videos are helping me so much! thank you!!
Great video! very helpful.
Idk how to do this because we are only allowed to use a + z score table
Cameron Huffman In that case you just have to take the compliment of it and find the corresponding z-score..but now it will have a -ve before it
Vishnu Sekar Yeah i ended up figuring that out, but thanks for the reply.
Thank you very much! Very helpful video
U r a life saver. Tq so much 🙏
Thanks 100+ times ..
You are a life saver
ima marry this video
Your videos are awesome
thanks man, you are a legend
I have a question:
Given that z is a standard normal random variable, find the z for each situation.
5.1) The area to the left of z is 0.2199
5.2) The area to the right of z is 0.6915
Help please
Thanks in advance
Great explanation
helped me alot! thanks! keep it up homie
That was really helpful, thank you so much.
Thank you so much with this 😘😘😘
It helps a lot.
Clean ❤
Impressive thank you
thank, you made it very simple
