Alternative Hypotheses: Main Ideas!!!

In Statistics, when we do Hypothesis Testing, we are supposed to have two hypotheses: A primary, or Null Hypothesis and an Alternative Hypothesis. This StatQuest explains why we need the Alternative Hypothesis, even though Hypothesis Testing tends to focus on the Null.

You guys have accompanied me all throughout my degree so I just wanted to thank you.

[AndrewCJXing]

I've taken statistical methods at a master's level but only knew how to get to the answer as I was told to and had never understood the small concepts' subtle and intrinsic meanings. Thanks for the video!

[avgspacelover]

I passed this subject with flying colors in undergrad but my true foundations are getting built through these videos, thank you so much!

[interoffice]

Not only are you teaching me much needed Stat concepts, your data examples from the last few sessions are also motivating me to get back into exercising..

[HazardousAbacus]

I'm a data science grad student brushing up on the basics. I found your entire playlist to be the perfect thing. I even went to your store and bought some study guides. Thank you so much for what you do!

[edwardmordrake]

Your teaching method is amazing, you break down complex concepts into simple bite-sized chunks. Super Teacher, Triple BAM!

[thearunrams]

you're way better at explaining this than some profs at one of the most prestigious universities in the world. can personally confirm.

[shanggao]

The explanation of why we don’t accept alternative hypotheses instead just fail to reject the null is GREAT!

[kstudy]

Sir, I really appreciate your effort. It is the best channel for study+ for fun + for easy understanding + for learning new things....Thanks a lot for making it easier .😊 I have tried to make these type of videos in past and it requires lots of time in that software and with that you are delivering best quality content and examples...So thank you much sir....

[bextuychiyev]

[Anthony-zpii]

I really appreciate this tutorial. It’s like a saving grace for my introduction to AI course
Thank you so much Josh

[alecvan]

Wow! Thank you for clarifying the idea of why we can't "accept" the alternative hypothesis—a concept that was always murky for me.... until now :P
You're the best Josh, thank you :)

[sanajafarkhani]
