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"

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.

You pay for the degree first, then the education

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

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! :)
