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
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. :)
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?
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
The 2 from the first example comes as a result of using the empirical rule. We want to know a range that captures 95% of our data. According to the rule, we'll need to look at 2 standard deviations on either side of our mean. :^D
is this just another way of stating the same thing you explained? μ ± 1γ contains approximately 68% of the values μ ± 2γ contains approximately 95% of the values μ ± 1γ contains virtually all of the data values
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.
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
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
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!!!!
So far 4 of your videos have saved me. Quick, simple, and to the chase. So helpful!
is it bad that I still dont understand
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 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!!!
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
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.
I love you 😭 I hope this helps me pass my stats quiz tomorrow
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.
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.
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!
I have a statistics test over this tomorrow and my professors never went over any of this. This was soooo helpful, thank you!
i read my book and my teachers notes but this video was IT. thank you
What a lifesaver! I went through multiple other videos that were unhelpful and you made it so easy! Thank you!
You are really my secret math tutor🤗
Thank you so much! You explain topics very well. 😊
Thank you so much after getting frustrated the whole day and scoring 22/40 I finally stumbled upon this video.
I got a test tmrw and i know im about to whoop it because of you. Thank you.
This was the most helpful maths video I have ever watched. Thank you so much!!
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
This just saved my math grade thank you
excellent saw before exam got my concept clear. love from INDIA
That was tremendously helpful. Thank you !!!🎉
Omgg thats so easy!!
Thznk you so much
I hope i can pass and do well in my exam
How do you know what the upper number is?
Thank you so much!!!!!
You explain it so easy! Thank you!!!

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
Great explaination. Thanks!
but how do i get the exact percentage?? i have a huge test tomorrow
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??
Guess who’s watching this on his midterm
Me😅
Saved my life thanks
Thank you sir..It helps me a lot.
Thanks a lot....very well explained 👍👍
Really excellent work 👏 man
it helped thank you
does anyone know how how he got 182.5 when doing the second example? he does 160 plus what?
thank you so much omg
You’re blessed.
what do we do if "k" ends up being a NEGATIVE 1, 2, or 3? do we just disregard the negative symbold?
Thats really great!
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?
THANK YOUU
Amazing, thank you sir
where did the 99.7 come from???
what does it mean if I get 0 for one percentage and 1 for another?
Wow thank you so much!
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
Tell me why this makes more sense than my text book and teacher.....
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?
How do I find the mean?

JEEZ THANK YOU!
how did you get 12?
thankyousomuch!!!
I appreciate you so much
What if you get an example where K=0?
thanks
Thanks, for making it simple to understad Empirical rule
saving me from my statistics test tmrw
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
using this mid final
the way you write 8 bro... bummy shi. good vid tho learned a lot x
I think all the good teachers make youtube videos and all the bad teachers work at the university.
I love you guy
where did the 99.7 come from
it’s a rule. Go to the second 0.40 he says it there
@@rachelis7484 thank you
Do I do the same for the 137.5cm like you did for the 182.5cm?
Should work if everything else is similar. :^D
I LOVE U
LIfe saver
for sure
Where did the 2 come from !?
The 2 from the first example comes as a result of using the empirical rule. We want to know a range that captures 95% of our data. According to the rule, we'll need to look at 2 standard deviations on either side of our mean. :^D
Like this video cuz he’s the goat
is this just another way of stating the same thing you explained?
μ ± 1γ contains approximately 68% of the values
μ ± 2γ contains approximately 95% of the values
μ ± 1γ contains virtually all of the data values
first view :))
Idk why you sound like dream
Thanks! :^D
WHERE TF COME THE 99.7%
got it
😭
Hang in there. Its a learning process. :^D
statistics is really so confusing🥲 i give up 🫠
well explained and the writting is neat and clean..saved me from failing in exam since i bunked my classes
thank you so much!!!
this video is literally a life saver, i'm freaking out cause i have my first stats test tomorrow
Thank you ! but You had me until the second example 😫 Why did you put K ? Does that represent the unknown percentage?
Thanks a lot!
Finals tomorrow 😂
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.
Fun fact for engineers, this information is important for random vibration.
best channel ever
Why did you use the top percentage (182.5) instead of the bottom range (137.5) ?
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.
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
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.

Thanks man, need it for a test tomorrow. Ur a life saver 🙏🏽
You didn't have to do the lower number? Why not?
How did you get the percentage 99.7%? From the answer 3?
thank you
