I finally got clear the concept of degrees of freedom only after watching your videos. Great works keep it up!

[@QuantPsych]

Thanks!

[@sonja5058]

I have to agree with Mendy, I don't understand why stats professors explain things by using more stats terms that they know their students are struggling to understand. Thank you for using human language! 😄

[@nadaelnokaly4950]

exactly!

[@astrid-w5z]

Glad I could laugh. When I can get jokes about a concept, then I know I understand the concept, to some "degree". Thank you.

[@AbdullaHernandez]

Lol this was awesome, despite super intense delivery it was really awesome with the old school 40s music, and made it feel wholesome. And very helpful metaphor.

[@imotvoksim]

My dude is a hypeman for statistics! Love it. Clear and engaging metafors, nice vid.

[@jkscout]

This has to be the best thing you've ever made for humanity. You made me smile. Thanks :)

[@hannaholding7742]

Dude, I love you. You are amazing in so many ways. Your enthusiasm and levity combined with simple real world examples makes a boring AF subject come alive in more than one way! In particular, it makes more sense!!!

[@hannaholding7742]

P.s also a photographer that is learning stats - albeit for psych ;)

[@hannaholding7742]

P.p.s this is Fred the partner of Hannah >.

[@chiawenkuo]

The best explanation of SD.

[@nathanthompson8652]

Brilliant, best explanation I've heard

[@outlawreader]

OK, this was amazing.

[@cassiefollett1461]

These are very good videos. Thank you for making them.

[@nadaelnokaly4950]

OMG I was looking for someone who can teach stats like this! your videos are awesome and hilarious 😂 keep it up!

[@larissacury7714]

Thanks!

[@QuantPsych]

No problem!

[@jekamito]

Finally I understood it! Thank you. I hope you can gret some milk and eggs for that nice boy.

[@soulcake76]

Your son is adorable! Give him all the ice cream he wants for breakfast!!!!

[@mayagoldstein1950]

Terrific 🙏

[@calenwu]

mf explains this in 6minutes while my computational statistics professor cant explain this in 2 lectures

[@paulbearcamps]

This was helpful. Thank you :)

[@amedeoottolenghi4132]

what is a numerator df and a denominator df

[@Dufflebags202]

Thank youuuuu

[@r.hainez2131]

Hi, you talk about your Jasp module. Do you intent to implement it into jamovi as well (the Flexplot module in jamovi is less complete than its jasp counterpart)?

[@QuantPsych]

Kinda. I'm actually going to collaborate with the maker of the gamlj module for the automation of model graphics, then beef up the flexplot part.

[@mikhaeldito]

Great video as always! I know spending a lot of DF is bad, but I never really get the reason why. This video helps!
EDIT: So then how's the remaining degrees of freedom used in a statistical test? Is it the actual "sample size" that we use to estimate our parameters?

[@QuantPsych]

The remaining degrees of freedom are used to compute P values. You may remember from intro stats that you had to look up the significant P value for a given test statistic (for example T), and for a given degrees of freedom.

[@mikhaeldito]

Thanks! By the way, I really like your working hours metaphor. It is much easier to explain IMHO.

[@soulcake76]

Hi! The link is not there for the paper you cited

It's there now :)
