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!!!

@chye789 4 года назад

Exactly! so many professors in colleges are not qualified.

@priyankasingh9790 4 года назад

Rightly said .

@JakeLo1991 Год назад

Sounds like a professor really got a 49% F-(Failure), but passed with extra credit 60% D-(Below Average) and that professor probably is going to be a journeyman- meaning getting fired or resigning from every education employment it gets.

i believe you are tagging someone here 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

@logarithm14 3 года назад

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

@MrSupernova111 8 лет назад

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.

@mp6412 3 года назад

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

@truvision7 10 лет назад

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!

@AugustNocturne 2 года назад

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!

@CharletteLin 10 лет назад

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!

@omjabe 2 года назад

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

@CoolVideoWatchpersn 10 лет назад

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.

@brandystanner8915 3 года назад

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

@grimslider75 11 лет назад

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.

@emailmesaleem 3 года назад

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

@miriamdusciuc4195 7 лет назад

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.

@location4898 9 лет назад

@Ag8MrE 10 лет назад

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.

@hamoudbirmingham 11 лет назад

Thank you sooooo much you can't imagien how much i needed this information !!!!! you are a live saver I love you

@samsazegar2973 10 лет назад

Excellent Explanation. I used your video to understand standard error. Most importantly you didnt forget to explain what the standard error means. :)

@nicolecruz3353 6 лет назад

you have saved me from my final great explanation wish my professor had the skills to teach like yourself

@shanayaranashetty 6 лет назад

@drpayalwavhal882 5 лет назад

You are awesome...I have an exam tomorrow and I hate any kind of math..thank you sooo much... you're my hero!!!

@elliew7704 4 года назад

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

@ishmael4489 4 года назад

Are there not two equations for calculating standard deviation depending on whether you're trying to find the population s.d. (σ) or the sample s.d. (s)? In this example have you not calculated the σ rather than s? =STDEV in excel automatically calculate the sample standard deviation, s?

@Makari126 8 лет назад

I have a question: Do you also use the 1 or 2 sigma notation for standard errors or only for standard deviations?

@sarahperron9669 8 лет назад

@monroe444444 11 лет назад

Thank you so much, great video. I just wish I knew when to use standard error vs standard deviation for the error bars.

@Longhairbeware86 11 лет назад

I second SnakesAndSticks's request for a ANOVA. Sorry, sir, it's just that you're such a clear teacher, and it's hard to find people willing and able to elucidate as clearly as you do.

@KhaLed-pb4pu 6 лет назад

yes and what does it mean? after drawing the SE bars? Does this mean that the higher the SE, the higher the variability in the sample?

@MEifi424 8 лет назад

@abbiejennings2282 9 лет назад

What do the error bars tell me? So how can I comment on them? What does a wider gap between the bars tell me as opposed to a smaller one? Thank you

@curtisqiu7837 9 лет назад

Abbie Jennings if the standard error is very big, then the data you collected might be less likely to represent the population.

@sadaquekhan 9 лет назад

what does standard error tell you in terms of significance and chance ??

@erkanbatti 7 лет назад

it was great. thank you

@neerarawat8094 4 года назад

How to calculate standard error of sample mean if standard deviation is in percentage??

@DrMichaelMoroney 9 лет назад

Nice explanation... I like the way that you have kept the video short and focused on the simplest way to achieve a calculated result. I guess it might be confusing for students when they go to Excel and find quite a list of SD functions to choose from? Also, I guess this movie references a legacy SD function from Office 2007... Wondered a bit too about dragging the formula across when the range for one set of data is only two cells and the other set of data is 10 cells?

@jordannewport6661 9 лет назад

+Dr Michael Moroney Excel ignores blank spaces. Also, I have Excel 2013 (and I assume this holds true for other versions as well) and simple stdev with no letters after it is available, so there's no real reason to not use the simplest one.

@fruitpunch4338 2 года назад

apparently there are two formulas for standard error SE = SD/√n and when two proportion are given SE = √(pq/n) also the SD = √(npq) so by substituting SD in the 1st formula we should get SE = √(pq) but it isn't, could someone explain how this works?
