What is the Chi Squared Model? where does it come from? how can I sketch it quickly?

I share some interesting characteristics of the chi squared distribution. good luck

What a blessing you are. You have no idea how many people you are helping.

As someone who spent years teaching in the classroom and OJT, the greatest asset for teaching, is for the instructor to be able to remember when they were learning and how confused they were. Teaching for understanding not grandstanding on how great they are. You are the only person teaching stat's and prob. on KZbin that has that unique ability. You are the GOAT.

Thank you! As someone who occasionally has to use such tests in the real world, it’s great to have an alternative explanation!

Mr. Nystrom is my favorite math teacher by far!

[@luisguilhermeleal3631]

To be honest, can't find anyone who explains statistics better than you sir! Your enthusiasm, the ability to make concepts palatable without cutting corners... amazing. A true inspiration for an aspiring professor like myself. Keep up the good work!

[@ariftans4593]

You are a real teacher ! (thumbs up)

That last sentence gave me a chuckle "Chi-Square for life" indeed 😄

[@reneeacosta4420]

Thank you Mr. Nystrom. ... For not letting the world ruin your greatness. Anyone who has been blessed to make it around the globe as many times as you....has most likely had many opportunities to let someone talk them out of their awesomeness. -It appears as though you have been able to hang on to yours. Keep letting your light shine... Let those who can't handle it... Go get sunglasses. 🙏 The world needs more mathletes.

Chi-square for life!

[@andreluispereira7507]

Glad you see you back onboarded Sir! Your explanations are lights to my data science training where teachers keep regurgitating formulas from text books ... if you could also explain the logic of some algorithms for some prediction models in a very didactic way as you perfectly do, I would say That would be the cherry on the top of cake!! Keep it up with the great work master!!!

Glad to see you pulled out the blue polo again.

Thank you

in the next video i.e. chi square 2 video, we calculated chi square value with a different formula than just summing up squares of Z scores as mentioned in this video. someone please clarify. thanks!

I always told students with low df it looked like a cartoon whale. The head is close to zero. The first time I introduce it, I will sometimes even add the tail and ventral fins. And a waterspout. Also, those four properties are really useful to know. Not sure if I ever learned those. The last one for finding the critical cut-off for alpha=0.05 is particularly useful because you don't need to look it up on a table (or equivalent, for the young whippersnappers).
