This is why dinosaur graphing should be taught as early as middle school.

[javidappledehli]

I like how the second set looks like it could be a marching band show

[luftbaum]

Well in lower dimensions thats a no-brainer, but if you got datasets with high dimensionality... whole different story

[jkid]

"Always visualize your data" cool I will just graph out these 215-dimensional survey results

[jensraab]

"This video was sponsored by Datasaurus Rex, your friendly neighborhood dinosaur."

[holybasilisk]

That was some life lesson.. From an unexpected source. ✨nice

[christopherjr]

Just imagine you run an experiment, visualize the data, and the graph is the datasaurus. XD

[wyattliu]

basically anything that summarizes stuff is a hash function that transforms from larger space to smaller space. In this case, compressing 2D scatter into a few numbers, we can easily get some hash collision

[evank]

This is what linear regression tests are used for: to determine how well the line of best fit fits the data

[trollme.trollmehard.]

I feel like I need more -- summary shorts don't tell the full story! :)

[LetoTheGodEmperor]

These graphs are discussed in Matt Parker’s book: Humble Pi !

[neuraaquaria]

That's why there's skew and kurtosis. 2 data sets can have similiar means and variance but they could be skewed differently with different kurtosis.

[timelessdocter]

Today I found out, a T. rex has the same summary stat as a star

[jortand]

my statistics professor used the Datasaurus Dozen example on the first lesson to show, always graph everything. And it was a good laugh to start out the course

[isaactfa]

Simpson’s paradox is an interesting related phenomenon.

[JamilKhan-hkwl]

What is the minimum number of parameters you need to fully explain the data? is it just all the coordinates of all the points? Issue with visualising data is that it is easy for 2D or 3D points, but difficult when you go to higher dimensions

[curiousScientistAndEducator]

And it's important to visualize them comparable.

[grantbeyea]

this is the earliest I've ever been to a youtube video

[rajinbraynard]

How about a parabola or fourier series instead of a line

[vidaimplicita]

Ha! News media needs a heads up on this!
