I use a lot of different tools including html5, photoshop, illustrator and string it all together in Final Cut Pro. As you can imagine it takes me a lot of time to create each video.

I have watched dozens of videos and read the reading assignments but none have compared to the simple and accurate way you explain stats information. You truly have a gift for taking a complicated subject and making it understandable.

You did a better job in 15 minutes than what my stats professor did in 3 hours. Thank you!

OMG, that could NOT be more clear. Wow you've got a real talent for explaining stuff. Thanks, man.

Words could not express how happy I am to finally be able to do ANOVA calculations on Excel! Thank you ! :)

BEST VIDEO I'VE WATCHED. completely saved me from having a meltdown over my coursework stats..... Legend, sir

Wow, thank you so much for the feedback. I really appreciate it! This has been my life's work. I hope you tell your friends and classmates to and help me ease their pain.

One of the best presentations I've ever seen! Great visuals and effective speaking skills, I wish all my professors and TAs were just as good.

I love the way you explained this. It made things so much easier to understand. Thank you!

To call this tutorial video superb would be a severe understatement. Absolutely excellent in every way!

a tide of relief washed over me as you explained this, and i was only having a break down about doing this with 20 groups last night! THANK YOU!!

Great to hear and thanks for the positive feedback.

You may have just become KING of KZfaq in my book!!! I just shared this in my Statistics class...YOU DA MAN!!!

You are the best teacher I have come across for teaching this statistics stuff. Keep up the great work!

Your video was really easy to understand and walked me through all the steps. I could not have done it without you.

David, thank you for your help! You and your videos are life savers! I wish I had seen them earlier this semester.

I just loved the way how to do ANOVA calculations !! Thank you so much. Keep up the good work

I have been trying to figure this out all week, thank you!!! You are an awesome instructor, please post more!

I have seen both this one and the previous hand calculation its very perfect, clear and simplified to understand, thank you so much and keep up doing such kind of illustrations.

Your visual method really works for me. Thank you.

Adding an extra minute to your video and showing how to obtain the Fcrit value from the table and comparing it to the calculated Fstat for hypotheses testing would have been the cherry on top of a stellar effort:)

Your're Awesome!! I'm from the Dominican Republic and me and all my classmates LOVE you! Biostatistics is a lot easier with you helping us!

Great job at effectively showing us how to do these calculations and what the calculations actually mean!

Thank you so much! This helps me with my research project tremendously.

Thanks! I plan on creating more and more videos and with more advanced topics as well. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help other students find the educational videos.

Time well spent! Videos are great! Very professional and easy to follow.

I like that - King of KZfaq! I do call myself the Professor of the Universe. Thanks for spreading the word and good luck in your statistics class. If you have any special requests of needs, then please let me know.

Very useful ANOVA knowledge. Your presentations are excellent!

Thanks for explaining that. It's easy to hit a button and let excel do all the work, but your lessons helped me understand the process.

You are very welcome! Good luck in your classes too.

Thank you so very much for making these videos. You have made it so much easier for me to understand what I am doing in my Statistics course! Keep them coming :)

Thank you for you kind words. Make sure you like MyBookSucks on Facebook (see link in video description). This will help me spread the word and become econometrics teacher for other students :)

It's Just Great Sir, I wish You were my Econometrics Teacher. Things looks so easy and simple, God bless you. Your videos have been so useful for me. Many Thanks

I would encourage you to watch the first video on the ANOVA playlist (I added a link to the video description of this video). This will help you interpret your results. Let me know if that does not help. It is probably best to post your questions as a message on MyBookSucks FaceBook Page since you can add attachments too.

Happy to help! Most statistics books seem complicate things and they are really expensive too.

Yes, you are right for sure and thanks for pointing that out. I do it the long way because there are still professor who require students to ANOVA the long way by hand.

Thanks for the step by step process, really helped a lot!

I owe you a great debt of gratitude.

Brilliant :) , Thank you so much, needed to get my head around this in a hurry, perfect and brilliantly taught!!

Thank you very much! Saved my life over here

Please don't listen to the negative comments sir, you are "not a stack of gold bars that everyone will simply love"...old mexican saying. Instead of simply saying thank you, I read that they wanted the results interpreted. It was my understanding this was simply a tutorial on how to plug in the numbers, at least that what I was here for having never used excel for calculations. Again, thank you thank you!

You are very welcome. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help other students find the educational videos.

You are better than any instructors I have worked with. You make it so simple to understand, I watch your lessons all the time and I have learned so much from you. Do you do any tutoring? I would love to work with you.

You sir, just helped me pass an important statistics activity in my AP Bio class. For this I am thankful. ~Sincerely, grateful stressed-out AP Bio student. P.S. YOU ARE AMAZING!

Brilliant video, thanks for explaining it so easily.

thank you so much for such a useful video, I had a big problem with this topic and now is solved. thank you once again

I appreciate your effort. Very informative and easy !!

Excellent tutorial. Thank you for taking the time to train.

I understand this a lot better than how my stats professor is teaching it. Thank you for breaking it down

Sir you are amazing I rarely comment in videos but you deserve more than a comment a subscriber and like thank you again

Answers 1. F Score can never be less than one. This is because you should square the difference between the observation - mean. This gets rid of any negative sign. 2. You could use a Cohen D to measure effect (would be one way). On my statistics fun channel I have a video on Cohen D, I would encourage to watch. Also, I have an entire playlist on ANOVA.

Thanks for this, made the data analysis section of my manuscript much easier :D

the perfect explanation i got here thank you very much sir............

Wow thanks so much. Good luck on your exams and in your class to. Do let me know if you have any special requests.

Very informative. Thank you

I guarantee I'll be USING you for the next 3 1/2 weeks, originally I was hoping to survive Bus Stats, I am now going for the A!!!

You can do it! That is awesome that you did not let your youthful age deter you :). Btw, I have lots of economics videos incase you have the need.

Good Explanation!

this has helped me so much, thanks

Top notch!!!!! Congrats!

Thank you so much. Such a great help!!!!

my professor was sick the day we learned how to do this, and his substitute hadn't taught Statistics in 10 years. Thank you, kind sir.

Thank you - saved my day!

You might be right about the spreadsheet usage. I am trying to make it as simple as possible, so students can follow it easily. I try not to use any short cuts or abbreviations either. If I was doing the spreadsheet for myself I would probably do it differently.

Amazing video , Thanks

very clear explanation.
