goodluck on your test man!
Thank you for you compliments. I use a variety of different software including photoshop, illustrator, HTML5, Final Cut, GarageBand and a few other products. Each video takes me a long time to create. My rule of thumb is each minute of video takes about 12 hours to create, so a 7 minute video takes me about 84 hours of development time. Besides the technology I use, I have done a tremendous amount of research on how students learn via animations and the impact of color and narration.

You made me understand statistics so much easier..well done!!
I'm a visual learner, and this helped me more than you can ever know! You spoke clearly and the animations were superb. Thank you so much. The world needs teachers like yourself :)
Yes I have a video on t statistics too (a whole playlist actually). It is hard to organize and sometimes even harder to find anything on KZread. I added a link to the playlist in this videos description. Like MyBookSucks on FB too.
This is a great tutorial. You talked slow and easy with really good animations. Keep up the good work, your doing well :)
Sir! This is hands down the best video tutorial I have seen my entire life. You have no idea.
Thank you so much for such a well though our compliment - much appreciated! Make sure you like MyBookSucks on Facebook (see link in video description). It will help me spread the word about the videos.
I've watched several stat videos, the way you do this video makes it so much easier to follow along and connect the dots. I'm not near as confused as I was before watching. Now on to see what other videos you have that might help me pass this class. Thank you!!
Wow this has got to be the best description ive ever looked at. Clean, Understandable, and overall fun considering math was never a strong suit of mine. Thank you for this excellent outline.
These videos are life saving! My stats teacher does not give us examples like this at all. You make stats tangible and workable.....thank you so much. I've shared your channel with all my whole class too!
That is great to hear! Thanks for sharing my channel to. Make sure you like MyBookSucks on FB (see link in the video description) and subscribe to this channel too because I am always posting new videos.
Thank you Deborah for the feedback. It is always good to hear from students. Also, make sure you like MyBookSucks on Facebook (see link in Video description) this will help other students find the educational videos.
Thanks for the compliment. I don't have anything on Binomial approximation yet, but it is something I do need to create. Good luck in your studies too.
Good luck in your data analysis class! Happy to hear the videos are helping too. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help other students find the educational videos.
This video is so helpful, love how you explain EVERY single piece. Thanks so much man!
Excellent video. I really liked the simplicity of it, you made it so easy to understand. I like how you took your time in explaining each aspect and the graphics included..way cool!
One word respect !! its just so perfect, it just melts into my brain. Your channel name is so appropriate. Love from Canada !!
This is the first video I've understood fully so far. thank you
This is the 4th or 5th video I have gone to trying to understand Confidence Intervals, you my friend have finally helped me understand. Thank you so much for being so clear and taking it step by step. I feel like the other videos assumed I knew given things, it really helped that you took it step by step regardless of prior knowledge.
Amazing!!! Finally someone who can explain this without getting unnecessarily complicated.
Wow! Thanks and it is great to hear my videos are lovable. If you have not done so yet make sure you like MyBookSucks on FaceBook (see link in video description). This will help spread the love!
You are very welcome! I always appreciate hearing how my videos are helping students. Good luck in your statistics class too. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
You are going to be my hero for the rest of this semester
So helpful! Really helps you get the basics down. I like that the video is short because it is easier to learn in small steps.
I'm in the joint Masters of Public Health and Masters of Public Policy program. Our public policy program is #1 in policy analysis that's because we go through a ton of stats and econometrics. I wish we had someone like you on faculty. I think the folks who aren't math wonks would love you. I'm definitely going to have the incoming class this year subscribe to your page for help.You are hands down the best out there.
Thank you so so so so much from South Africa. I was really struggeling with STATS until I found your tutorials. No it all makes sense. All my fellow stats students agree that you are the Superman of stats lecturers !!!!!!!! Again, thank you so much.
So glad I found you! Your explanation was clear and to the point and you make Statistic so much easier to understand. THANK YOU :)
You have helped me ace my statistics class. Thank you! You do such a great job at simplifying this subject so it makes sense!
I have been trying to make sense of this for the past week. You have a gift for teaching! Thank you so much!!!
I've got a Stats test tomorrow and these tutorials are helping me so much! Keep it up!
Thank you! I will definitely put those topics on the list for future videos (especially the probit models) because I am always looking for ideas. Btw, what are you studying at Berkeley?
It depends on what type of problem you are trying to solve. You would use proportions (the equation on the right) when you have percents. You use the equation on the left when you have points (or numbers) including a mean and standard deviation.
Great to hear and appreciate the feedback back. Good luck on your Six Sigma exams (if you plan to take them).
In all videos that I have watched this video is easier to understand than others! Thank you
YOU CANNOT BE ANY CLEARER !!! WOW!! AMAZING!! If I had ten thumbs, I would have raise them all up.
finally someone who make this stuff easy to understand!! thank you SQUARED!!!
@AmyOneal1523 I will include some examples of rounding -- thanks for the suggestion. This is also a great question for your professor. Where does he/she want you to round. In my classes the whole number if fine because statistics is all about estimating anyway.
so simply explained. you made it sound easy compared to others.. thank you so much
The coefficient comes from the z score table and I do have some videos on how to read a z score table. The name of the playlist is Normalized Tables Z scores Bell Curve. You tube does not allow me to add links otherwise I would.
You would have to work backwards. It may be easier if you go to MyBookSucks on FaceBook (see link in video description). You could take a photograph and attach it to the message. Then I can respond.
Interesting you mention the microphone. My daughter is a musician and helped me set up my microphone (with a pop filter). It was really not that much money and you are right it does sound much better.
OUTSTANDING PRESENTATION! Dude I am so thankful that I saw this. You are AWESOME!!!!!!!
I loved this explanations, one of the best I have heard! instant subscribe. Thank you sir!
Thank you for taking your time, and even making this video. I appreciate it!
Great to hear the vids are better than your book and they are costing you a lot less to :). As one student told me that "MyBookSucks and it is expensive too/"
Thank you so much for your comments. I am trying to get the word, to help even more suffering students. I just started a facebook fan page "MyBookSucks" as well.
Wow! All this time.... I thought it was so much complicated than I really thought. Thank you so much!!! I understand it now.

Davon Matthews You are very welcome. I have long thought that statistics not that difficult, but the books are bad and it is often taught poorly. I appreciate you took the time to write to me.
Make sure you subscribe as well because I am always posting new material.
You just saved me 2hrs of trying to figure this out on my own! Thank you!
Wow, I honestly cannot thank you enough for your videos! I was considering withdrawing from my Statistics class before watching these! You've made it so simple to understand. Thank you!
Perhaps you prefer MyBookSucks? Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
Thank you! I really appreciate your method of delivery , step by step, and easy to follow.
You are welcome! Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
Helped me finish my Stats homework. I am taking this class online and will definitley be looking into more of your stuff to help me out. Thank you!

Good luck on with your online class. I have heard those can be very frustrating for students.
That would be good if you shared the link. Also I am open to ideas and suggestions for new videos that students need/want. Good luck in your Masters program as well.
Logan, thanks for the compliment. I appreciate it. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
Really loved this video. Very thoughtfully made and executed! Finally able to make sense of some of this stuff haha. Thank you thank you thank you!!!
Thank you so much for such kind words.
I love questions! First you would take the average and standard deviation of the series of numbers. The confidence coefficient at 95% is 1.96. Once you have these three items you can follow the steps in the video. Make sense?
You are the greatest! Sonny back from UC Berkeley again and I'm reviewing all of the statistics I covered throughout the school year so I don't forget it. You have a knack for explaining things. You saved me in grad school this year, seriously. You wouldn't happen to be any good at constructing Logit and Probit models would you? hahaha. And maybe you can explain to me a Oaxaca binder Decomposition. j/k. Thanks for everything though!
you are a absolute champion, i was pulling my hair out trying to answer these questions, thank you!!
these vids are awesome, so much better then reading from a textbook
Excellent explanation! Thank you so much for doing this video!
Brilliantly explained! You have a real gift for teaching!

How simple you made this concept. Thank you very much.
Great vid! Thank you. What software do you use to make this video?
That is is a good idea because it is hard to organize videos in KZread. I am building a website that will be organized much like a text book, so students can easily find the topic they are looking for. I will do that for each of my channels (statistics, economics, calculus, and algebra). In the meantime, I would encourage to like "MyBookSucks" on FaceBook. The fan page is light heartened including some college humor, my freshman id, etc.. Thanks again for suggestion.
The number depends on the level of confidence. 1.96 represents a confidence of 95%, 2.58 represents a confidence of 99% I just added some links in this videos description on z scores and normalized tables. This should help you understand where the 1.96 comes from.
This was extremely helpful, thanks so much!
Don't pull your hair out! Happy to hear the videos are helping you. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos and not pull their hair out :).
Extremely organized and well thought out. 🙌🏼🙌🏼🙏🏻
Good question. These are for samples. "I am 95% confident my population mean is within the confidence interval I calculated." I should have mentioned that explicitly. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help me spread the word about the educational videos.
Wow. Instantly subscribed after your explanation.
I added a link in this video's video description. If you click on "show more" You will see the link.
even until today your teaching is very helpful😁
I am taking Statistics and Introduction to Six Sigma and Process Improvement which is difficult. You've explain this to me perfectly.Thank you
This tutorial was easy to understand and it helped me to understand how to perform the calculations. Thanks.
. You are very welcome from Kansas City -- right in the middle of the USA (no beach for a lot of miles!).I have never been to Jamaica, but it is a place I would like to go someday -- looks like a nice place
I find I do not even need to pause these short little lectures, and I understand clearly! You can teach me more in 6 mins, than any of my professors can in a 2 hour lecture. It would help if ALL of them had a slightly better American accent. Thank You! ~ Sarah (Sophomore @ UWGB)
Nice video. Very informative. One thing I want to know is what kind of software did you use? I would like to use it to explain different topics to people. Thx!
awesome. thank you very much. make some more, your way of teaching is enlightening.
Well thank you! Your comment is much appreciated.
Thanks a lot for the effort, would you please send your explanation reg. competence coefficient ?
Very nicely done Sir !! Much appreciated 🙏
Great video. Plz keep up the good work.
Absolutely amazing!!! I am going through stats right now and I am having trouble understanding confidence intervals. Especially, with the normal approximation to the binomial to find the probability. Do you have anything on that? and thank you.
Amazingly, simply put. I think education would be more interesting if it was taught this way. When you see it in the book, it can be quite daunting. Thank you very much.
Thank you, thank you, THANK YOU. You explain it way clearer than my professor.
Fantastic video. Thank you sir.
Why aren't real life teachers like that..? thanks a lot.
Thank you for your tutorials. I also really appreciated that you are using real audio equipment and not some cheap $5 mic! lol The audio sounds really nice when it's coming out of a pair of KRK's Rokit6's (with M-Audio C400 interface) and it actually make learning more enjoyable when I don't have to setup a compressor and gate because of the line noise caused by the owner of a KZread channel using cheap equipment!! lol
Great video! Can I apply the same to each Likert answer?
Thank you soooo much! Taking Data Analysis now, every little bit helps!
Thank you. You've helped me. Subscribed
Really really good way to explain it!!!
This is so much clearer than what my teacher gave me! Thanks for your help!
