Hypothesis testing #1: Basics (no maths!)

Type 1 and Type 2 errors explained from 9:02

A biiiig shout out from Singapore, Justin! I am a frequent YouTube user for educational purposes but I was so selfish that I had never left a single comment on the videos I viewed, but I really wanted to give a comment this time and say I sincerely appreciated your videos. It is so important to teach the learners the concepts first, develop their intuition and help them understand the logic behind the concepts. I feel like I have learnt nothing if the teacher says "oh just use these formulas and you don't need to know why they work, but they just work in this and that situation". However, in order to address real-world problems, you need to know what are the tools you have and apply them correctly. As computer science and AI develops, it looks like we can skip many steps to achieve a goal, so understanding a concept thoroughly seems very time and energy consuming and even not as important, but those who hold onto the basics of their areas have the amazing power to create and develop, and they are fast learners and flexible enough to survive in this rapid-changing world. Apologize if my blah-blah sounds very old school or even stupid, but I personally enjoy videos like this and I can't wait to watch more of your videos. Hope you can continue spreading knowledge this way!!

I love how you build on the basics! I can’t expect to understand the hard stuff if I don’t establish a foundation first. You explain all of this so well. Deeply grateful!

You're literally saving lives. Thank you.

this non mathematic video lead me to discover the next videos.
Thats what makes this presentation so enticing
THanks prof you made me enjoy Statistics <3

[FrictionBearings]

the production quality of these videos is just immaculate!

[dayanandasilva]

what a great teacher, brilliant , very clear pronunciation so that easy to understand each word and the way you explained is marvelous

[alomgirkabir]

I referred your videos to my friends. You explain amazing.

[Jfm]

Thank you for providing such a clear explanation and introduction to Hypothesis testing.

[taamcyat]

Wish now and back then when i was in school that you could have explained maths, stats like this! You basically explain the invention and reasoning of the formula. Teaching cant get any better!!!

[mariangelysantiago]

Definitely, the best explanation for Hypothesis that I have ever seen. Being honest this concept for me is really contradictory, and it has been a little difficult for me to understand. But your videos had helped me a lot. Thanks.

[SuperSudharshana]

Well explained and easy to comprehend. Thank You!

[Competent]

Nobody could have explained it more easily than this. Thank you so much💯

Dear Justin. Very well made videos. I really like your approach. You first give an intuitive understanding and then jump into the Math. I agree with Vicky Lin - conceptual understanding is so very impt before you jump into the tools. Sadly though, neither the students are interested, nor the teachers have the ability to break down esoteric concepts in simple language, like the way you do.

[shivgaur]

Thank you so much for explaining the concept so well!

[solankiankit]

You are sooo good.. wish I had some one who taught stats like You do.. brilliant work man.. sooo good..! Thanks for all the efforts of making video

[matthews]

Great Video! Can't wait to get an A on my upcoming test!

[fawadmahdi]

Great video. Please make more of such videos which are easy to understand

[МадиТемирболат]

Hi. Thanks much for your videos!!! Could you please explain next quiz: in the first example you've taken two samples each n=20 and came up with sample mean lower then Ho, but presume that first random sample gave us mean that is close to Ho. Does it means that we need to stop further sample taking and decide that Ho is true?

[dododeadbozo]

Just a small thanx for making it easier to digest!
