I hope you discuss ANOVA in the future. First time I understood degrees of freedom. Also it would be really cool if crash course website had some work sheet excercises for these topics.
Best explanation of the topic. Bees example is a killer one and also the Credit Card example. I wish we had such brilliant teachers at grass root level, so that maths does not feel boring and hard. Thank you entire team of Crash course.
@10:17 Any person knows why the denominator is (s1^2+s2^2)/2, different from the pooled variance from the two-sample t-test? Why is the variation divided only by 2? Is it just the case that Effect size use the different denominator than the two-sample t-test?
Appreciations for a very nice initiative by introducing dialogue box which will help a lot in depicting what you all actually want to convey...many times..
Ok, first half of the video I didn't get anything (as always), but when they started to talk about how practical significance is just as important as statistical significance and stuff, then I went: "Oh, so that's what you're talking about!" xD
You might not need both other pieces since it's a credit card number. Those numbers have a Luhn checksums on them so one of the digits is completely determined by the others.
Until here it was excellent! Perfectly scripted. However here using large complicated numbers made it hard for me to digest the concept. My brain tried to place those long digit numbers in a formula while trying to understand the concept. Maybe simpler examples could help those like me, people with low IQ with maths. Though using bee sample is really genius.
Its sounds as though each resource has all degrees of freedom until which they are assigned.. so degrees of freedom is not intrinsic, but yeah in order to do something useful we must forego that freedom..
DFTBA Studios renamed itself as Complexly sometime in 2017, if I remember correctly as per the plans of the Green brothers. The merchandise website remains as DFTBA.
Its seems weird silly and logical.. The way we try to solve issues is trying to measure data and go back and change things until we see some change.. This is how a dumb computer tries to do things.. however we have powers of awareness that can improve things.. i.e. we should be looking at outliers looking for reasons why something has or hasn't worked.. i.e looking for variables.. I guess variables are degrees of freedom too?? we keep changing variables until we see better p and effect sizes. that leads to some understanding . I guess this is what machine learning is doing well..
thought this was going to be on the freedoms allowed by differing government types. Instead it was this useless garbage. Too bad channels are afraid to post anything substantial anymore.

The explanation of degrees of freedom in the credit card thief example was a stroke of genius
didn't understand it at all...
I have an exam on statistics (especially multiple regression) in two days and this just helped so much!
This is an awesome series! Explains so much! I am surprised it's not more popular because this knowledge is much in demand on the job market...

Avocado drop at 0:33
Very observant!
Wow, I would have never noticed. Most important comment ;-)
New meme: sumbody touched mahvocado!!!1
That Mean Thief bit would make a great children's show idea
Brilliant example for degrees of freedom. Thanks a lot.
Actually, everybody's credit card number HAS an effect on other's, because it excludes that number!
0:32 the avocado moved !!!!
CrashCourse rocks! Thanks for the uploads!
Jack Draak I wish this existed when I was still in school. What a great supplement to a statistics course.

idk, I think its because you want to test the effect size from the 2 groups so n must be =2

No
The credit card e.g. was awesome
This is awesome. Hope you guys do regression and forecasting too.
Brushing up on my econ subjects since I have never used them.
There are SOME very intelligent videos on TH-cam (this is one of them).!
3:04 you will never know where you are on any distribution until degrees of freedom are removed - which they never are (n-1)
I saw your plush of BOO the dog. RIP Boo.
That bee example is hard to understand. Where 5420 comes from? Why is there 100 under the square, but they tell about 99?
I miss the little bamboo plant. I hope nothing bad happened to it. 😟
I love with your channel
I liked the avocados in your table, they look very tasty.
Amazing way of presentation , Superb.
Can you teach us about Artillery Only?
LOL, I have statistics quiz in hours and here I am.
Missing a Video on ANOVA, great series
could you guys do one about mono hybrid inheritance
#28, and i still dont understand! 😌
If you want this free forever, you can pay for it!!

Don't forget the "security code!"
Aw, I thought this was going to be a crash course engineering degrees of freedom video..
PLAY ARTILLERY ONLY!!!!!!!!!!!!!!!
Stealing a credit card number is not identity theft! At most it's credit card fraud if used.
this women does stats and econs damn
Wonderful thank you
I still prefer Celsius
How about crash course business law

Cuomotep the Reluctant Libertarian cheers mate
DFTBAQ!
isn't degree of freedom usually represented by 'K'?
No not really. It is usually represented by n, as in the video
Or df.
The chicken dance was totally not necessary
why is the channel dead
i thought was a philosofyc one, i've studied this on the college xDDD
???????

Honeybee populations should not be worried about! Be concerned about the rapidly declining biodistribution of naturally occuring bees!

SQUAAAAAAAAAAAAAAAAAAAWK
Could you have used a more confusing example... 92342523423512
Degrees of freedom, I barely knew her
So that's statistics of freedom. Where is dynamic constant number of freedom? I guess it's 50 stars on 'murican flag.
her jokes are so cringieeee
waste of time too long
Did you know gaming is a better channel

Are you kidding?
Well, you could watch CrashCourse World History or other playlists for such information. This is CrashCourse Sabermetrics!
Degrees of freedom are important part of Statistics.
