You're a life saver! Ive started normal distribution for my upcoming s1 exam and been struggling with the questions that had z with negative values. now i have a much clearer concept. THANK YOU!
you are teaching it in a simple yet fast way to understand, I have spent hours watching khan academy (which is great because it explains everything to the smallest detail - but sometimes not fast enough since I don't have all day), and I should have been watching instead! Thanks
Could you explain why in statistical inference one should never standardize a variable according to a sample distribution of the same data and why that would be circular reasoning?
Thanyou so much this is really helped but i have a doubt ! when finding probabilities above the standard deviation you subtract the probability of getting less than that standard deviation from 1 but you cant do that right beacuse that probability you are subtracting from one is only lesser than the standard deviation not lesser than pr equal to right ? anyways thanks a lot this really made things clear
hey so where could I find the probability fraction for a sample of 8.24 (3sf) standard deviations outside of the mean? I know this will be a very long number but I have an ongoing dispute with some individuals. I say their Hypothesis has to be incorrect because if not we have data that I now know is 8,.24 (3sf) standard deviations from where it should be. I use this to say their hypothesis is highly likely to be inaccurate. though some of that data will be 11.43 again to 3 SF standard deviations out. obviously their conclusions are absurd but if I can quote actual fractions for these it makes my point even more powerful.
This is very helpful but I have to calculate P( ˆp ≥ 0.26), which I get, P(Z ≥ 0.662) = 0.2539 I don't understand how my professor got 0.2539?? Can you help me understand? I thought, I should round 0.662 down to 0.66, which gives me: Z score of 0.66 = 0.7454, so i then do 1 - 0.7454=0.2546. If this is the correct way, how did my professor solve for "0.662"? Any help is appreciated, Thank you, Ali
+Ali “Tech Geezy” Sabbah Your mistake there mate, was that you rounded down in one of the early stages, they say to never do such a thing as it will decrease your accuracy and therefore give you the wrong answer in the end, hope this helped, if you need any more help just contact me :D
ExamSolutions I did good, all thanks to you. I had to start studding in one week before the exam and you're vids are the ones that saved me. Thank you so much sir!
Never give up!
Thanks
Best maths teacher EVER! Thank you! This is so easy now! My teacher made it so much more confusing than it needed to be!!
Steady on but thanks and i am pleased you understand it now.
your videos are still helping people out in 2020!
You're a life saver! Ive started normal distribution for my upcoming s1 exam and been struggling with the questions that had z with negative values. now i have a much clearer concept. THANK YOU!
All the best to you.
Your voice is so soothing, makes the process so much easier!
P0p
i know this is late, but thanks so much, my teacher made this so much more confusing than it actually is! Thanks so much for the great video!
just been sat here for 2 - well more like 4 hours trying to figure out what you just explained in this lil' vid!
thanks mate
This is so helpful thank you so much! You've literally helped me go from a U to an A in maths in 4 months and I'm not even joking

Well done.
Your explanation is soooo good . Thank u
Well explained, you made it clear and simple. Thank you.
Thanks you so much sir. I have never been this clear about Z before. You're the best teacher I have known so far!! Thanks you so much!!
You're welcome.
Thank you so much, awesome video. Thank you for making it free I really appreciate it. Thanks mate.
omg thank you so much
beero elabani You're welcome
U buddy are amazing mashaAllah!
I have my exam in 8 days and you taught me what my teachers were trying to teach me since september in 8 minutes and 15 seconds. Cheers kid
How did the exam go :)

it helped a lot to refresh my statistics. thank you
I love you. You just saved my life.
+just existing Another life saved. That's good.
Wow man thanks for this video, I'm definitely going to be checking out your other stuff.
Amazing video! I appreciate how much effort this must take to make but nevertheless it is highly appreciated by many as students like myself :)
Thank you for all your videos ...... you are genius
Great video, I love your channel!
Brilliantly explained!! Thank you so much!!
Thank you very much! i was about to give up on Normal Distributions.. till i saw this video! :)
It is a greek letter Phi for our letter f
Thank you so much I love your videos
Appreciated, thanks.
Cheers.
you are absolutely brilliant
Great job!
Cheers
You are simply amazing
I do not know what I should say ! U r awesome ..... :)
Very helpful!
Legend. Thanks a lot!
great tutorial. thanks heaps
Thank you SO SO much!
Cheers
Hi Stuart,
What was that notation that you used? it sounded like figh or something?
could you do a video with how to use the percentage points table with examples...i find it so confusing... thank you!!
man you are amazing for real , damn it looks so simple coming from U... keep up
Thank you sir
No problem, thanks for watching.
NICE VIDEO TO WATCH
thanks a lot!
thank you

thats ayoba & amaizing
life saver
thank you man!
atlas i got it.
Could you explain why never standardize a variable according to a sample distribution of the same data?
@sciencerocks1995 Thanks
why didn't you cover area between 2 points???
ohhh soooo easy !!!!

hans kalsi hi Hans I need urgent help in statistics a level rn in minor steps, I’d really really appreciate if you could help me out
THANSKS I:)))))
You're welcome. Best wishes.
my table does not show thy of Z, so how do I work that out?
Change playback speed to x1.25...
You're welcome
what meaning of Z~N(0,1)
LEGEEENDDD!!!
so then... how do we solve P(Z>a)=0.244??? find a...... answer is 0.759..... i just want to know how to solve...
exam is tommorow
I wish you every success. Good luck.

Your website its downnn ahhhhhhhhhhhhhhh
cant get any easier !
Did you say "FIRE" 1.5? 0.0 I didn't quite catch the word..
your sound changed!!
Thank you!! So insightful and easily understood!
