How To...Calculate the Confidence Interval for a Sample

[@mma_sap]

Just learned a whole month of class in this video right here. You really the man

[@dtacherra6063]

its 1 week worth for my summer class.

[@illianmckray6786]

My teacher who was trying to teach us this content had over an hours' worth of content that still failed to accurately explain how to do this, your video was so much more helpful, thank you!

[@neerajbhardwaj2784]

Don't underestimate that lecture, How many questions you can solve from 8 minutes of video as compared to 1hour long lecture?

[@yiijung]

Don't compare it just the way you focus.

[@toni-anngayle5909]

Thank you so so so so so very much. I have been struggling with this for almost 2 hours. You made it so simple, and your video is so concise, yet so impactful.

[@Pahulu48]

fancy seeing you here. love you

[@atavierreed2267]

same smh

[@frndssuchi]

So much clarity and such a easy way to teach. Appreciate your teaching style so much. Thank you for these videos. Love and respect from India 🤗

[@rramos2020]

I have been searching on how to solve this problem and you WERE able to break it down and i was able to follow without any problems. Thank you

[@DixieMQ]

I'm back leaking for your stats guidance. With your teachings I passed stats at the community college. Now I'm at the university. I'm back for more assistance. Thank You for all you do. Sending infinite blessings.

[@aaa-uc6el]

saved me 3 hours of lecture, what a hero

[@kelseymills146]

I have been struggling so hard in my statistics class (first math class in over 5 years), and feeling like I just can’t grasp any of these concepts. This has helped me understand so much, thank you so so much for the amazing lesson!

[@Bob50520]

Beautiful and clean Eugene O'Loughlin. Wild how good that 6:58 min video was.

[@collins0052]

Thank you so much😭 I’m doing my assignment right now and couldn’t understand the teacher that was supposed to teach me this. Thank you for such clarity in how it’s done.

[@PatoLorenz]

I truly appreciate your by Hand video series. It has been incredibly useful in my studies

[@michaelpappas3857]

Thank you Dr. O'Loughlin! Wonderfully clear explanation.

[@Valerie-yt9zj]

Thank you so much for your help. Im in the middle of confusion and some how your way of teaching, talking and interpreting make me feel safe and calm. Like everything all have its solution. I know its sound rediculous but thanks again.

[@xinhuacao338]

Thank you. You manual calculation videos are really show the essence of statistics. I always use Minitab to analysis data, actually don't understand how to get the results. Your video helps a lot.

[@alisonhesse8575]

THANK YOU SO MUCH!!!!! YOU JUST HELPED ME PASS MY FINAL!!!

[@ABUBAKARRIBRAHIMKABIA-cs1nq]

Thanks very much sir. You just save my day. I have an exam to write in an hour time. Thumbs up for this video👍

[@mitch6151]

The teaching is so clear and great. Thank you!

[@jessicasophiedouie2275]

This video explained this very clearly and made it so much easier. Thank you so much. You're an excellent teacher

[@Livia.S]

I had no clue on how to calculate this but after watching this video I can confidently say I will never fail this.

[@deltax7159]

your videos are always so straight to the point and helpful, thanks for everything you do.

[@trevorpope1913]

Thank you, your videos are excellent, it makes so much difference when you work by hand and explain why and how.

[@benjaminblankers4645]

you explained it very clearly sir, thankyou!

[@mayrasingh-v1l]

Great video! It's super easy to understand and you speak very clearly and at a good pace. Thank you!

[@zeyadelhalaby5282]

thanks a lot I was struggling among many articles and stuff ..Bless you and healthy always

[@christineshavrnoch979]

You just explained it to me so that it “clicked” thank you for making this easy!!

[@khushbusubba1144]

Your so cool, professor Eugene! love your teaching method, it's so easy to learn from you. Thank you so much. Respect.

[@nathaliarocha6979]

I can’t believe I finally understand this, thank you so much!

[@mahiraamirova781]

Excellent, professionallly, absolutely clear. Thanks. Let Allah Bless you

[@ukieeebeats725]

you're solid my guy

[@siyungjung7162]

Thanks a lot for your clear and detailed explanation.

[@scotturbanski740]

This has been so confusing and you made it so easy. Thanks!

[@maanavkapur9273]

Concise, clear…what a guy

[@mikekorsak373]

Your video was an excellent review - simple and succinct --- thank you!!!

[@bigseekersb]

I've seen other sources that state you can't estimate the mean with such a small sample size (n=14) unless you already know the original population data is normally distributed. That requirement was not mentioned anywhere in this video.

[@diminarchy]

Isnt the t distribution for that? Wouldnt it be a z value for n>30 (im genuinely confused so pls weigh in lol)

[@jabbedcrab]

@@diminarchy yes, that’s the exact reason why we use t-dist. We also don’t use T If we are given the population standard deviation.

[@hectorsosa7687]

This was soooo helpful! Thank you for posting it. I was so easy to follow

[@celinemary2914]

I've learnt about finding confidence level after watching your video.

[@arlenecampbell3877]

I thank you for making it so easy to understand.

[@ryanakmal6411]

One of the clearest explanation!

[@sumitnaik164]

thank you. you explained it very simply...

[@inna1929]

Thank you, Professor! You helped me out so much on this problem. Many thanks!

[@eleazararce5716]

Great video and came in right on time! Let me see if I can get the right answers now.

[@MunirAhmad-sv7nd]

This is helpful . Thanks professor for this video . Comment is from Pakistan

[@logesh5071]

thank you for the assistance, I will pass my exam because of you

[@marynakshanovska344]

Thank you so much, professor!!!

[@wong4728]

OK it is in, Teacher Extraordinaire. Thank you for this.

[@SweetDamolaShekoni]

You are the best professor

[@CometSpy]

Thank you, teacher!

[@ripbellx]

sir, you are a godsend. thank you so much for the informative but brief video!

[@travistatman]

6:25 all of this is a great walk thru but the interpretation is incorrect. The correct interpretation is that for 95% of all random samples, the confidence interval will contain the population mean.

[@abdulazeezolakunmi361]

Absolutely, his interpretation is treating the population mean as if it were a random variable. But it is fixed.

[@Rawennnnn]

Really helpful! How to calculate confidence intervals of variance (n under 30)?

[@pillainag5378]

Fantastic teaching. Thank you

[@tasha6734]

Please break down the how you found the x bar, s and n.

[@abby_plascencia7297]

Thanks for help! This video helped me so much more than my professor!! Keep up the great work Sir 😀

[@yvettestrandberg6267]

Your videos are so very helpful Thank you very much again!

[@frielruambil6275]

Thanks alot you just helped me to answer my assignment questions 👏

[@serhatkoroglu6708]

great narration thank you

[@jst7675]

I watch this always if i forgot how to calculate lol ty dude btw

[@paulmckenna9927]

Easy to understand... at last. However, there are 4 results in the list of weights that are outside the CI range. 4/14= 28%. I thought that in a 95% CI range there would only be a 5% chance of having a result outside of the range

[@jasonmiller4490]

KZbin professors trump normal professors any day of the week, thank you for the great video

[@nataliadejesus972]

Thank you very much for the explanation through this this video, it's really make me understand

[@rajbhushan3541]

great video sir

[@jeenjoy7358]

what if your degrees of freedom is 199? how do we find the values there?

[@aditya4974]

Perfect explanation! Thank you so much

[@vialeyrichards4244]

very good job sir

[@nthabisengnathalie1135]

This was very much helpful, thank you.❤️

[@TheWaites]

Amazingly explained - Thank you!

[@mayrasingh-v1l]

Great Video!

[@GreenYoshi3881]

I feel like I am not learning much in my current statistics class. KZbin has become my new professor and the only way I am understanding it which is sad. 😢

[@statuscrew4335]

Very helpful love from 🇵🇰

[@mohamid2k438]

thank you so much for the help friend

[@michaelrussi9209]

Thank you very much Professor Eugene!!

[@stephenf368]

Thank you!

[@FakeID-v6p]

So it was this easy😂😂😂😂 Im kinda mad at myself for failing to grasp this, but then again i had procrastinated and did it in a rush👁️👁️😂

[@missrossiya]

watching stationary calculations is so satisfactory :)

[@thordarareach]

Very useful sir❤

[@Societyofknowledge]

great video and easy to follow!

[@celinemary2914]

Compute for the minimum sample size using an appropriate formula. Assume that no similar study has been previously done and that the level of variability is unknown. Use 2% level of precision and 90% level of confidence. Could you please explain this to me sir!

[@grosssaft3700]

my teacher needs to make notes

[@poppy2976]

you're doing god's work

[@BraveGisgo]

great video!!!

[@Baljindersingh-nb9jy]

Very clear explanation. Thanks

[@alleahshane3345]

what if it is not mean but a sample space, the sample space cannot be seen in degree of freedom. which is 47

[@kaylakai]

very useful, explained very well, thank you!!!!!

[@courtneygrant-xi4yc]

YOU ARE AMAZING!!!! thank you so so much

[@infiniteheartnig3413]

Love you ❤

[@erik9817]

Nice, and what if my T table only has one-tail?

[@stanley510]

this is the best work❤

[@nataliekay5566]

This video was so so helpful youre the best

[@thilankavithanage1891]

That was very clear. Thank you.

[@Lauren-mq8nm]

I'll try this today

[@johnralphbone8092]

Why'd you make it so easy, and why does my teacher make this so freakin hard

[@englishaccentcoach7419]

Really it’s useful but why you multiply critical value with SE

[@gabrielareyesreid6737]

Genius! Thank you so much

[@theearthling8178]

Thank you very much! Was very helpful.

[@ernestol6325]

Thanks, professor! love the style and comes across easy to understand!

[@smr0018]

Very helpful, thank you so much.

[@zachhutchison5574]

your voice reminds me of the youtuber great scott, good video though very easy to follow

[@josphellihsilak4588]

So concise.

[@antoniopanoflo123]

...and this is a confidence interval from only one sample, correct? No bootstrapping because that would be too long of a process, correct?

[@AngelAdeniji]

this video REALLY helped thx
