How to Interpret Error Bars

Error bars are an important element on graphs, and allow you to make statistical inferences at a glance. Here's how to interpret error bars, and the difference between confidence intervals and standard error bars.

This is probably the most straightforward explanation about Standard Deviation, Standard Error, Confidence Intervals, and Error Bars. Thank you so much!

most simple explanation ! made my life and thesis easier

Does the length of the error bar equal twice the error?

Hi great video. I’m writing a practice paper - and the question is asking me to explain (using info from the graph provided) weather this is a significant difference between (the average temp rise) it’s a bar graph with standard deviation error bars. The biggest bar has a massive error bar with the middle of it meeting the top of the bar. I think that one has a large variation in results - so there is a significant difference? Another bar is very small and has a small bar. But the error line almost takes up a third of the bar. So this one is much harder to tell. Maybe there is a significant difference maybe there isn’t??? Okay so this is a hard question and I’m wondering if anyone can lead me in the right direction.
Thank you :)

For the error bars is it important to consider the underlying probability distribution?
I assume that for the confidence interval somebody already thought about that in order to get such interval.

what about percentage uncertainty error bars

[hosnaeftekhary]

how do we do that "formally"? 3:00 I mean how do we calculate the error without error balls and eye balls?😁merci

Confusing. Why not use one example, stick lots of different kinds of error bars on it, and show what the different bars would mean using the same backdrop.

Your like begging earned you a dislike too.
