- Statistics 101: The Binomial Distribution.
In this video, we learn the basics of the binomial distribution using the simple sales performance data of two salespersons. Given a fixed success rate and call volume, what is the probability of closing a certain number of sales per day? We use our knowledge of basic discrete probability distributions, the binomial experiment, and a second example involving quality control to explore this very important concept. Enjoy!

The positivity that the video starts out with is so refreshing and very much needed. 💛
hye Angee. I have just posted a video on Binomial Distributions as well. I hope it will be helpful.
I know. It makes me really motivated
I'm typically a positive "I can do it" person, but statistics has become the class I wish I never had to take. The break through's are great when they come but I've fallen about a week and a half behind in understanding... almost 2 chapters and the break through's are not coming enough. It's like looking for something specific in a crowded dark room as someone else is trying to shove more stuff in the room. God help me!!! Your videos are helping a little though. :)
You're a wonderful teacher! Thank you sir
Hey Brandon I great to be back you helped me a lot when I first did my certifications in Six sigma around 5 years ago and now again during my master studies, can't thank you enough for your great lessons hope you are thriving! Cheers
hye Juan, I have just posted a video on Binomial Distributions as well. I hope it will be helpful.
minute 1:00 - the most inspirational math video ive ever seen!
Thank you! The positive energy at the end brought me to tears. I really needed to hear that.
U are blessed in ur profession...The clarity with which you take us through is just amazing. God Bless You Brandon !!!
Thanks for the uplifting words of wisdom at the beginning of your video!
Thank you so much! Probability and Statistics is new to me and most of the time I could not "see" why we had to do each of the calculations. You made this so much easier for me to understand the why to the point I can finally do the calculations.
A truly great video! This was my very first time being exposed to the topic and everything was as crystal clear as it could be, huge thanks!
Brandon you explain so well and I love your positive and encouraging attitude. You're wonderful. Keep up the great work!!!!
I'm MBA student, and I found this video is very helpful coz I'm using it as a base to understand Quantitative analysis. Thanks a lot
I cannot thank you enough for the thorough explanation! I'm struggling in Stats badly and this really helped clear the fog!!
Saw this on Google...sure be nice when this class I'd behind you. Xxmom
My teacher cant seem to teach our class this over the course of a few days, but this man manages to do it in one sitting! Genius! I'm definitely subscribing! :D
Brandon, I very much enjoy your tutorials. I completed the Six Sigma training in which there is a great deal of probability and to be able to have your tutorials has been very much helpful. Thank you very much for taking the time to share your knowledge!! Please keep doing what you are doing!!
Thank you so much for taking the time and explaining the concepts. Def an inspirational video and way of teaching!
Thank you for making this video. It has moved mountains for me.
You are an exceptional mind my friend. You even helped me clear up some basic, elementary math concepts. Thank you so much for decomposing this problem the way you did.
I swear somewhere from minute 20 to 25 I was saying, "Ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!"
Haha! Thank you! I am glad you found the video helpful. All the very best, B.
Thank you so much for this explanation, I just had a light bulb moment for sure! You're AWESOME!!!!!!!!! I feel like I can pass my Statistics class with an A. Will keep you posted!
you are an amazing teacher
Hi Brandon, you make understanding stats fun. Love the words of encouragement, I sense the sincerity. Please keep doing what you're doing, don't change a thing. Thanks!!
Thank you very much, this was really illustrative.
Thank you for your effort and positivity!
Awesome! Thank you so much. People like you make the internet a better place.
My exam score thanks you as well.
This is amazing work you put out here. Can't point on anything I would change. Clear sound, great graphics and a nice tempo.
This was really helpful! Thank you, I love the encouragement at the beginning and I would like if you put exercises for us to practice at the end, and if you do that please mention the answer because I'm having trouble finding questions that have answers, to practice on. :D
The way you explained binomial distribution is priceless. Never knew the idea behind the equation before watching this video.
Thank you Brandon. A wonderful explanation.
oldeubank You very welcome! Thank you for watching.
Thank you for your videos. I will be watching every single one.
Was getting confused with "success and failure" and your video on Binomial distribution really help me clear up the confusion.
Brandon !!! That was really helpful.. You made it really simple !! Awesome !!
Mateen Ahmed Awesome! Glad you found it helpful. Keep on learning!
Love the way you derived Binomial equation without using any algebra. It is very intelligent and builds intuition for practical application of the concept.
Thanks for the great material, I really like your encouraging comments at the beginning of your videos, they're very kind. Greetings from Mexico!
Great again. Your more fun than the book! Again, thank you and keep making videos.
Thank you Brandon. Very clear explanation makes it easy to understand. God bless.
Love love love! Thank you so much for creating this video!
Thank you very much. Great teaching!! very clear steps and it helps me to understand better.
Thank you for making these videos and your kind words!
All your videos are amazing. I learned statistics watching your videos. thank you much Brandon
Love your videos. So awesome. Been out of school for such a long time that these are amazing refresher courses.
This video is very clearly presented. I am a statistician by training, learning the subject in university 50 years ago. Through Foltz's videos I am getting new understanding of what I learned half a century ago. A bit late but still lots of fun.
This is really counter intuitive !!. Thanks. This is an amazing explanation.
Brandon your my hero!
Thanks for all your help. Please keep rocking!!
Simple and easy! Thanks for doing this video👍
Thank you so very much! You explain things clear and simple, which is needed with a subject like statistics. Thanks too for the motivational tidbits at the beginning and end. :) Please keep making videos for confused students like myself!
I have watched many of your videos and found them extremely good. Your are a talented teacher who understands well his material and understands the needs of the followers. I have only one wish: using examples that belong more to real life situations. I am a physician and an epidemiologist, so I prefer some examples related to health. Thank you so much
Thank you so much, your videos really help me understand subject matters that initially look impossible to me
Hi Brandon my GURU, Thank you for making topics so simple and thorough. You are great at teaching. Thank you for putting so much efforts for us
Very Helpful Brandon! Thank you for making!
Brandon, that was awesome. It made the subject much clearer for me. Thanks!
thank you so so much for the free course, help me a looot with my career change!
I am beginning to understand discrete probability and binomial distribution. Thank you very much for this class.
Thank you Brandon!!! I am learning this for my AI cognitive project and I hope this helps me a lot in my career!!!
Thank you so much for uploading this video
Excellent. A wonderful explanation. Keep up the good work sir. God Bless you.
Another very nicely done explanation! Thank you
Great message and examples. Thank you.
Best explanation on youtube
This video provides a very good intuitive understanding of the reason behind the formula
Thank you for your comment. Each selection of 5 items is a discrete event. This is literally, 'walk over to the machine and take the next 5 items.' At 17:53 I point out that n=5 is the number of trials; each individual item selection is a binomial trial; success or failure. No matter how many times this 5-item selection is repeated, the probability of an outcome never changes, in the same way a coin flip never changes. Doing the selection once is the same as doing it 100 times.
Thanks for the brilliant explanation!
Excellent explanation !!!
Thank you so much for this and other videos. One comment: Unlike what's stated at 32:00, I think Margo's higher prob. for 6 sales a day is NOT because she's making more calls. It's actually because Joan is more productive than Margo and so has a higher prob. of making 7 or 8 sales (in her 10 calls), while Margo has a higher prob. of making only 5 or 6 sales (in her 16 calls). In other words, because Joan is more productive, she will less likely make only 6 sales and more likely 7 or 8 than Margo.
This is what I was thinking, too.
GURU you are awesome...I tried a helll to learn but you made my life easy....
Thank you for this video. Very helpful in my Statistics course!
Thank you so much! Great, informative video. ❤️

I love your motivation speech and the quotes before your lectures @ Brandon sir.
such an encouraging person, he should b a mentor
Great lesson. Many thanks.
You are a good teacher. Congratulations!
This is a great video for teaching Binomial Distribution. I wish I found it sooner. I did appreciate your intro comment about feeling overwhelmed, because I was. THANK YOU. Just one tid bit of info, at the 31:27 point in your video I saw one typo in the probability formula. You typed in .55 for Margo in the (1-p)n-x part of the formula, instead of .45. The math you did was from the correct value. Just wanted to let you know in case anyone else got a little confused.
... You are very good at teaching complex concepts.
Very simple and sweet.
After 10 years of first studying this thing today is the day it clicked. You sir are a god
All the work you did before led you to that moment. Kudos to you for the perseverance to keep going!
This is very educative. Thanks for this video
