You're an amazing human being. You've made everyones lives who watched your videos a whole lot easier. Uni is rough man, and youre making this stuff a breeze. Hope everyone who needs it sees your videos and hopefully we can bring in the ad revenue you need to keep doing these vids
Thank you so much, dude. I was so confused about this stuff in my class, so I saw your video and tried to solve it, and it worked! Again, thanks so much, man your the best, and you're a great tutor. Have a great day, man.
my teacher taught this and everyone… actually knew what to do.. but the people in this comment section are making me feel so much safer :) and the video was amazing! Thank you!
For getting the k value for sd, why we are using upper range/value not lower range/value? Or can we use both, if so then the sd would be changed for rule
You make every problem seem like 1+1=2, when my instructor explains it, she's alllll over the place and makes it so much harder than it has to be. She also adds solutions that aren't even asked for in the original problem.
This is so tempting to do for problems. This is because a lot of things are connected. For the videos I put in a bit of time coming up with a problems and sticking to the core idea. This helps keep me from wandering. :^D
so by normal distribution for the first problem, would you say the distribution would also be either symmetrical or uniform? My statistics class uses different terminology on this.
Sir? how about suppose that at least 68% of scores in a normal distribution fall between a score of 7 to 10. you need to find the approximate mean and standard deviation of these data. i dont know how to solve it. can you help me?
doesn’t the mean and median need to be the same to be a normal bell-shaped distribution? I found the my data is skewed to the right, yet 100% of the data is within 2 SD from the mean.. did I do something wrong?
I went through an entire doctoral program, and this is the first time it's understandable to me. Thank you for this, and I'm sorry for disliking your passion so much. A lot of people dislike mine, too, so I feel your pain. I'm sure I'll be back. :)
Hi this was a very helpful video, Thank you:) I was just wondering why for question 2 you did not also find the k value for the lower number in the interval?
as I understand it...he did give you the K value once he solved it for the larger number. because its the same std (3) one is just plus and one is minus - the problem already gave the weight ranges. hope that helped.
Suppose IQ(intelligence quotient) scores of people in the world is normally distributed with a mean of 100 and standard deviation of 16 A)what percent of people have IQ scores between 85and 115 B)provide the range of IQ scores for 99.7% of the population Can you solve B one I have solved A one please

You’re a literal lifesaver! Got a quiz due tomorrow and 4 homework assignments and I had no clue what I was doing! So helpful!!!!
crazy how I learned more form this than my stats class.
We are on a same boat

Fr bro
Currently in an MBA and taking Managerial Statistics. Ive learned more from 3, 5min youtube videos than in 9 hours of lectures.
I hate ap stats
well explained and the writting is neat and clean..saved me from failing in exam since i bunked my classes
So far 4 of your videos have saved me. Quick, simple, and to the chase. So helpful!
I learned more from your free examples than I ever have from my college stats class THAT I PAY FOR
You're an amazing human being. You've made everyones lives who watched your videos a whole lot easier. Uni is rough man, and youre making this stuff a breeze. Hope everyone who needs it sees your videos and hopefully we can bring in the ad revenue you need to keep doing these vids
Your 5 min video helped me understand something that my teacher couldnt explain properly in 1 hour..thankyou so much.
I have always said that for being a good educator you need the gift and the passion. And you have both ,bro thanks!
I struggled for two days on some Stats homework about the empirical rule. Watched two minutes of this and BAM I understood it. Thank you so much!!!
this video is literally a life saver, i'm freaking out cause i have my first stats test tomorrow
I am shocked at how simple you made that!!! Thank you so much!!
Looks like I might pass this class after all. Thank you for making it feel so simple!
who also is addicted to these paper and pen videos . these people's explaining skills are on a different level
Crazy I couldnt understand it in my statistics class today. But you were so good at explaining it so you learned me to understand this term.
Thank you so much, dude. I was so confused about this stuff in my class, so I saw your video and tried to solve it, and it worked! Again, thanks so much, man your the best, and you're a great tutor. Have a great day, man.
This is the best explanation from entire RUclips
I love you 😭 I hope this helps me pass my stats quiz tomorrow
is it bad that I still dont understand
Thank you sir! Had trouble on my last two questions and you clarified it very well and made the two questions much easier to understand.
What a lifesaver! I went through multiple other videos that were unhelpful and you made it so easy! Thank you!
my teacher taught this and everyone… actually knew what to do.. but the people in this comment section are making me feel so much safer :) and the video was amazing! Thank you!
Thanks man, need it for a test tomorrow. Ur a life saver 🙏🏽
i read my book and my teachers notes but this video was IT. thank you
I think all the good teachers make youtube videos and all the bad teachers work at the university.
I have a statistics test over this tomorrow and my professors never went over any of this. This was soooo helpful, thank you!
Thank you so much after getting frustrated the whole day and scoring 22/40 I finally stumbled upon this video.
You are really my secret math tutor🤗
Thank you so much! You explain topics very well. 😊
This was the most helpful maths video I have ever watched. Thank you so much!!
Thank you for breaking this down so well; I have a learning disability, and my fast-paced statistics teacher's style really doesn't stick with me.
I'm cramming for an exam rn and I cant express how thankful I am
That was tremendously helpful. Thank you !!!🎉
I got a test tmrw and i know im about to whoop it because of you. Thank you.
For getting the k value for sd, why we are using upper range/value not lower range/value? Or can we use both, if so then the sd would be changed for rule
best channel ever
Thank you ! but You had me until the second example 😫 Why did you put K ? Does that represent the unknown percentage?
excellent saw before exam got my concept clear. love from INDIA
You make every problem seem like 1+1=2, when my instructor explains it, she's alllll over the place and makes it so much harder than it has to be. She also adds solutions that aren't even asked for in the original problem.

This just saved my math grade thank you
How do you know what the upper number is?
Great explaination. Thanks!
so by normal distribution for the first problem, would you say the distribution would also be either symmetrical or uniform? My statistics class uses different terminology on this.
Finals tomorrow 😂
Guess who’s watching this on his midterm
Me😅
Hello sir!
Is that 68,95 and 99 remain fixed for one, two and three standard deviations in spite of changing mean value in each question??
Omgg thats so easy!!
Thznk you so much
I hope i can pass and do well in my exam
You explain it so easy! Thank you!!!
Why did you use the top percentage (182.5) instead of the bottom range (137.5) ?
I should’ve found you last night and not 30 minutes before my test but thank you 🙏🏻💞💞
Tell me why this makes more sense than my text book and teacher.....
Really excellent work 👏 man
Thank you so much for the explanation
How did you get the percentage 99.7%? From the answer 3?
but how do i get the exact percentage?? i have a huge test tomorrow
Sir? how about suppose that at least 68% of scores in a normal distribution fall between a score of 7 to 10. you need to find the approximate mean and standard deviation of these data. i dont know how to solve it. can you help me?
Saved my life thanks
Thank you so much!!!!!
what do we do if "k" ends up being a NEGATIVE 1, 2, or 3? do we just disregard the negative symbold?
what does it mean if I get 0 for one percentage and 1 for another?
doesn’t the mean and median need to be the same to be a normal bell-shaped distribution? I found the my data is skewed to the right, yet 100% of the data is within 2 SD from the mean.. did I do something wrong?
in the second example, how did you come up with 99.7%? just a little lost on that part lol
is it because the standard deviation is 3?
@@laurencarrizales8318 I’m confused on that part as well
Thank you sir..It helps me a lot.
Thanks a lot....very well explained 👍👍
Would you have to do standard error of mean in the same format ?
does anyone know how how he got 182.5 when doing the second example? he does 160 plus what?
Thats really great!
What if you get an example where K=0?
I went through an entire doctoral program, and this is the first time it's understandable to me. Thank you for this, and I'm sorry for disliking your passion so much. A lot of people dislike mine, too, so I feel your pain. I'm sure I'll be back. :)
No worries. Math can be frustrating, even for people who study it.
I'm glad this video was able to help you out. Keep up the good work. :^D
If you don't mind my asking, what do you do when you're subtracting and trying to find the percentage? And in what situation would you be subtracting
also thank you for the video, this saved a lil bit haha
This guy just saved me
Thanks for this!
AMAZING! Thank you!
where did the 99.7 come from???
How do I find the mean?
Thank you,
Sir!
Fun fact for engineers, this information is important for random vibration.
You didn't have to do the lower number? Why not?
Hi this was a very helpful video, Thank you:) I was just wondering why for question 2 you did not also find the k value for the lower number in the interval?
as I understand it...he did give you the K value once he solved it for the larger number. because its the same std (3) one is just plus and one is minus - the problem already gave the weight ranges. hope that helped.
Wow thank you so much!
Thank you so much!
how did you get 12?
it helped thank you
Why the K? Where’d it come from?
why do you have the mean as x bar and not mu?
x bar is what we use for the notation when we are talking about a sample.
mu is the mean of a population.
thank you got a 100 percent on my quiz after not understanding my teacher at all lol
Nice work! :^D
Amazing, thank you sir
THANK YOU!!! :)
Bro saved me my teacher speaking broken English I ain’t understand shit 😭
Do I do the same for the 137.5cm like you did for the 182.5cm?
Should work if everything else is similar. :^D
thank you so much omg
I appreciate you so much
You’re blessed.
saving me from my statistics test tmrw
JEEZ THANK YOU!
Thank you sir!!!!!!!!
Suppose IQ(intelligence quotient) scores of people in the world is normally distributed with a mean of 100 and standard deviation of 16

Can you solve B one I have solved A one please
Thankyou ☺️
thank you
where did the 99.7 come from
it’s a rule. Go to the second 0.40 he says it there
