Standard Error

Paul Andersen shows you how to calculate the standard error of a data set. He starts by explaining the purpose of standard error in representing the precision of the data. The standard error is based on the standard deviation and the sample size. He works a problem and gives the viewer a problem to work on their own.

Standard Error of Data Set 1: 3
The error bars should extend from 9 to 15

It took you seven minutes what a professor couldn't do in 2 hours...
This is a very clear explanation of the idea, thanks!!!

[logarithm]

My teacher went over this, along with standard deviation, and literally explained nothing. This helped so much, thank you

You're an amazing teacher! I came here because I am short on time and won't have time to finish reading the textbook before a deadline I have today. I'm fairly good at statistics and I was amazing at how simple you make the subject for just about anyone willing to learn.

Your remarkable ability to calmly explain without rushing is so appreciated Sir, thank you.

[truvision]

Excellent! You teach straight forward and totally understandable, you sir have a great gift for teaching. Problem is most teachers forget to explain what these terms even mean leaving the student totally lost until practically the end of semester when one good explanation of what its for would have sufficed!

I do not understad why professors make this topic so difficult, and this guy makes it so simple.. GRACIAS!

[CharletteLin]

Thank you. =)  I'm about to briefly review Standard Error in a class, and your way of explaining it seems much simpler and clearer than the way I was going to do it!

[AugustNocturne]

I've been confused several times before over this concept but you have made it very clear. Now I know what the standard error is and why it's important. Thank you!

[brandystanner]

I'm a teacher, and I watch your videos before I teach anything so I can teach it better.

[emailmesaleem]

so the Standard error calculation of the second set is 10.61 which what tutor asked us to comment, unfortunately nobody did :), Thank you Paul

[Echo-op]

watched bozeman sci for ap bio when i was in hs now watching stats to review for grads school. bozeman hope u see this n know that i cant thank u enough

[Arthur-fzdw]

Thanks for your videos, 8 years later, still super useful! Even for a PhD student like me haha

[changa]

Best explanation I have ever seen! Thanks!

[CoolVideoWatchpersn]

Helped me with genetics and cells last semester and now in semester two hes making stats easy to understand. Thanks Mr. Anderson, you have a real nack at teaching a diverse range of topics i commend you.

[LovezYouful]

I CANNOT EXPRESS HOW MUCH YOU'VE SAVED ME WITH SO MUCH HOMEWORK AND STUDYING. YOU ARE A GODSEND THANK YOU SO MUCH

[grimslider]

Simple and Practical; I firmly believe you actually DESERVE to be on youtube, in light of all the unclear, under-produced and unhelpful videos out there.

The SE is an estimate of the SD of the sampling distribution. That is, if you were to take heaps of samples from the population (and because they are samples and estimates of the population mean with some error, each sample mean would be slightly different), and took the SD of those sample means, that would be (close to) your SE. It is only an estimate though.

to find Standard Deviation on a TI-84 plus, Stat:edit: {enter data in list one} then enter; Stat: Calc: 1-var stats: calculate. x̅= mean & the fourth data line (which looks similar to Sx) = the standard deviation

[miriamdusciuc]

Thanks for this video. It was really straightforward and helpful. My stats instructor could learn a thing or two from you. He tends to be all over the place. It makes it very hard to follow what he's saying.

[gideonfortune]

Straight to the point extremely helpful
