I cannot tell you how many hours I've spent trying to understand this concept. Every video I've watched has been unclear or just to complex for me to visualize and understand. I literally paused at 1:34 and just sat there for a solid minute cause it was that simple. I'm amazed that no one has ever explained it like this to me, including my Stats teacher. Thanks so much for this!

[@statquest]

Awesome!!! I'm glad the video was helpful! Yes, it really is that simple.

[@rahulshah26]

That's crazy, I read this comment as I'm paused at 1:34 !

I was looking for one sentence....the sentence that made my day. The standard error is the STANDARD DEVIATION OF THE MEANS😎

[@user-bz7fj1fk2m]

The standard error vs The standard error of (the) mean. Am I right?

[@nyetoska]

hell yes. I was waiting for this all my life.

[@zyansheep]

*ignores last 3 words*
"The standard error is the standard deviation"
NANI?!?

Why cant school just say this^^^^^ to explain this like holy its not that hard to dumb it down

And he didn't charge $25,000 for it

[@JagoBridgland]

Fourth video watched from different sources on standard error, this was the one where i paused the video at 1:34 pointed at the screen and said "That makes sense" out loud to myself. Simple explanation is key, thanks a lot

[@statquest]

Hooray!!!! I'm glad my video was helpful. :)

[@TheKubbas]

THAT'S EXACTLY WHAT I DID! Paused at 1:35, stared at the screen and went "WHOOAAAAAAAA!!!!"

I work in data science. Took masters level courses from many professors for a lot of $$. These videos are much clearer (and better) IMO

[@statquest]

Thanks for the endorsement! :)

[@statquest]

Jason St George I'm glad these videos help fill the gaps in what is taught in classes. I was always pretty slow when I took classes - so I made these videos so that I could make sense of the material - I'm a visual learner, and the stuff I learned in classes was all based on equations, which I had trouble learning and remembering.

[@TheAlerb]

Agree, I am here cuz im taking a statistic signature in master :P

[@raygivler]

I have to piggyback on Mike's comment. I tried Harvard's EdX in data science (which I advise everyone to avoid at all costs), and the explanations were just disparate terms, equations, and R code. I am sticking with Josh. The Harvard/Edx system even marked me as passing one of the 9 sections, but they LOST MY DATA somehow. Even after I sent them screenshots showing the display of my passing in their system, they would not update my account and mark me as passing.

[@qpellidomombre]

You pay for the degree first, then the education

[@alecvan7143]

Crazy how simply something that seemed so complicated truly is-thank you Josh!

[@statquest]

Thank you! :)

[@criticalmaz1609]

Thank you! I don't know why my professor couldn't just explain it like that. I have dyscalculia so I need something to visualize in order to understand abstract concepts like this.

[@statquest]

Happy to help!

[@frontroom]

Why all my profs make this so difficult I will never know... But what I do know is that this video helped me understand it instantly and simply. Thank you so much!

[@mintr5767]

holy crap. I'm an undergrad psych student doing a long distance course so most of my learning is driven by myself, and the statistics have been driving me insane; I just don't understand it at all. this video is SO simple and something I've been struggling with for WEEKS is finally clear. thank you SO much I literally owe you my firstborn

[@statquest]

Bam! Glad I could help!

[@staceytaranto7092]

[@StuffOffYouStuff]

Jeez! By far the simplest explanation of what the standard error is! You win! Thank you.

[@statquest]

Thank you!

[@flagshipbuilds]

Thank you for the clear and simple explanation, as I am visual learner. I re-phrased it to my understanding/textbook. Please clarify/advise: Standard deviation quantifies how much a data entry deviates from the mean, within a data set.
Standard error quantifies the deviation of multiple means from the true mean, from multiple data sets.

[@statquest]

That is correct! You've got it! :)

[@flagshipbuilds]

@@statquest Thank you for your help!

Thanks!

[@KathrynOBrien-lv7ss]

when I was taking notes on this in class it made so much sense, and as I went back to study my notes and saw "standard deviation of the means of the means" I literally could not figure out what that meant, so I am very grateful for this video and the visual representation.

[@rakeshbhatt8412]

This was a new information for me. However, I'm not able to understand how (and why) are we calculating standard error for single set of observations (having only 1 mean for the set). Shouldn't standard error be 0 for any single set of observation? Can someone please clarify?

[@statquest]

The reason we can calculate a non-zero value for the standard error from a single dataset is that the raw data gives us an estimate of the raw variation in the data. Once we have that estimate, we can estimate how the mean itself would vary, given how the data itself varies.
