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.
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.
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.
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
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!
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!
This video is misleading since it does not mention that the data points should be the means of different samples. Hence, the mean he is always referring to is the mean of the means!!
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.
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!
THANK YOU Mr Anderson !! ... made this so much simpler than my university waffle. From now on you are my go to for stats. Turned this into a complete red pill/ blue pill moment ... (sorry could not help myself).
Just put 99% into the box in the Descriptive Statistics tool instead of 95%... To calculate 99% instead of 95%; the value is equal to +/-2,33 for one side and +- 2,58 = z for both sides for evaluation. M -z*SE < M < M+z*SE.
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.
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?
+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.
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?
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?
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
I need help with this question. A survey of 500 adults showed that 240 of them drank alcohol daily. Calculate standard error for the adult population that drink alcohol daily and also construct the 95% confidence level.
yaay I got it right I feel sort of now I can understand epidemiology but sorry for the fact that this is my last semester to have ED course why!! I just understand it thanks professor
Why dont we just used standard deviation as error bars instead? This also shows the data being more or less spread out. What is the added benefit of standard error?
Anyone reading this - I need help now! Got A2 ISA in a few hours. On the calculator, I have ox (sigma x) which I think is population deviation and sx for sample deviation. This video shows sx being used but my teacher, in excel, got the value I get for population deviation as he said sample would be unrepresentative and population covers more??? WHICH ONE DO I USE??!!!
What is the rationale of calling it the standard error of the mean? The mean is not used to calc it and the value is not close to the mean but is put around it. Would make much more sense to use call it Standard Error of Xi (or std).
I understand standard error of mean and standard deviation, but I'm confused about isn't that all of these two show how spread your data is, what's the different? help?
who is here for ap bio
Yup 🥲
😢me
Sadly yes :(
It's the most miserable anything I've ever encountered
Im literally taking this as a freshman help me 😭
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.
I'm A Nursing Student, But still These Things Are not Leaving me :D Thanks for the easiest explanation.
helped a lot, thanks
It took you seven minutes what a professor couldn't do in 2 hours...
This is a very clear explanation of the idea, thanks!!!
Exactly! so many professors in colleges are not qualified.
Rightly said .
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 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
My teacher went over this, along with standard deviation, and literally explained nothing. This helped so much, thank you

on the verge of tears

+Bozeman Science why are you so good at what you do?!?! :)
It was fantastic, I really lovely
Your remarkable ability to calmly explain without rushing is so appreciated Sir, thank you.
SEx̄ of data set 1 = 3.01.....I think lol. Thanks for another great vid :)
Thanks for your videos, 8 years later, still super useful! Even for a PhD student like me haha
Simple and Crisp
Step by step guide....perfectly explained, thank you
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.
it would be grate if you could put video on student T test.
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!
Straight to the point extremely helpful
Yassss I love this channel and MR. ANDERSON!!!!!
Why does looking at the standard deviation not give you an accurate enough picture of how good your data is?
life saver
I'm a teacher, and I watch your videos before I teach anything so I can teach it better.

THANK YOU Mr Anderson !! ... made this so much simpler than my university waffle. From now on you are my go to for stats. Turned this into a complete red pill/ blue pill moment ... (sorry could not help myself).
I do not understad why professors make this topic so difficult, and this guy makes it so simple.. GRACIAS!
you explained this better than my Professor did with her obsolete ways.
In your example of .826/sqrt10, why didn't you rationalize the denominator?
we need more professors like you.........
what does standard error tell you in terms of significance and chance ??
i lo u king
Very clear and well edited, great video :D
Extremely useful Thanks a bunch
do you have video for calculating 95 and 99% confidence interval
Just put 99% into the box in the Descriptive Statistics tool instead of 95%... To calculate 99% instead of 95%; the value is equal to +/-2,33 for one side and +- 2,58 = z for both sides for evaluation. M -z*SE < M < M+z*SE.

Read the definition of «standard error» in radiotherapydictionary.blogspot.pt/2016/11/standard-error-se.html
Best explanation I have ever seen on Standard Error. Thankyou :)
Very simple n lucid explanation
And to think you are actually a Biologist...damn man you are just awesome :D
Thanks for the video, it was VERY helpful :-)
Thanks, Paul! You have explained this very clearly.
This is actually really easy. Thanks a lot!
Thank you Mr. Anderson! Good and clear presentation!
shit, you're good!!
I needed this, thank you.
SE(X)👍
Oof

Connecting this to regression would be helpful....trying to figure out how that fits in with the regression equation.
Great video - Thank you for taking the time to make this!
Am I the only freshman taking ap bio?
it was great. thank you
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
Abbie Jennings if the standard error is very big, then the data you collected might be less likely to represent the population.
eğer bir gün eğitim bilimleri çalışmak için bu videoya kadar gelirsen lütfen haberim olsun :)
i am a big fan of you buddy. it really helps me clear my doubts specially when i need to understand these concepts for my research at doctoral level.
Really very simple and clear. Thanks!
In the time it took him to talk about doing it, you can calculate the standard deviation.
{([12-9]^2+[12-15]^2)÷(2-1)}^0.5 = 4.242640687
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?
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
Thanks a lot sir. God bless you.
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?
That was helpful, thanks!
5:28 I don't understand where 3.16 came from? If 826/10 square root then the answer is 261. 20 (2.d.p). So where did 3.16 come from?
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
I need help with this question. A survey of 500 adults showed that 240 of them drank alcohol daily. Calculate standard error for the adult population that drink alcohol daily and also construct the 95% confidence level.
Isn't the SE for data set 1 2.12 not 3? B/c the SD of 9 and 15 is 3 and then 3/squareroot of 2 = 2.12 ??
W00 Mr. Anderson you rock. "Standard error is one of my favorite statistics..." Why is that so adorable to me. 😂
Thanks so much! This video was a great help! =D
*Studying Soc Sc (Psych).
What about probable error how we get it
ty
Did he just say, "Mr Anderson"?... Did he take the red pill? Or the blue pill?...
Thanks very much for your explanations. Every time I watch one of your videos I am enlightened.
yaay I got it right I feel sort of now I can understand epidemiology but sorry for the fact that this is my last semester to have ED course why!! I just understand it thanks professor
I don't get what's the point of standard error. Why can't we just use standard deviation to tell us how precise the data is?
Standard Error of Data Set 1: *3.00000000204*
You should teach in Harvard
Why dont we just used standard deviation as error bars instead? This also shows the data being more or less spread out. What is the added benefit of standard error?
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?
You are awesome...I have an exam tomorrow and I hate any kind of math..thank you sooo much... you're my hero!!!
Its crazy how I can't understand any of this Maths until I get to your video then then lightbulb pings and I suddenly get it!
i love you so much mr andersen
Many thanks for your easy and helpful explanation.
How to calculate standard error of sample mean if standard deviation is in percentage??
Does someone know WHY this is the formula for the Standard Error? Where does it come from?
Can't believe it was that easy once broken down like that. Great help. Thank you!
thank you so much, I was really confused until I saw this vedio.
You deserve much more credit! Thank you for everything u do for us clueless high schoolers!!!!
Anyone reading this - I need help now! Got A2 ISA in a few hours.
On the calculator, I have ox (sigma x) which I think is population deviation and sx for sample deviation.
This video shows sx being used but my teacher, in excel, got the value I get for population deviation as he said sample would be unrepresentative and population covers more???
WHICH ONE DO I USE??!!!
Turtles.
+TooGood LMAO!!!! rekt
Can you please guide me that how can we interpret standard error more than 1 ( for example between 2-5)
you have saved me from my final great explanation wish my professor had the skills to teach like yourself
What is the rationale of calling it the standard error of the mean? The mean is not used to calc it and the value is not close to the mean but is put around it. Would make much more sense to use call it Standard Error of Xi (or std).
Teacher you are so best!;⊙
I understand standard error of mean and standard deviation, but I'm confused about isn't that all of these two show how spread your data is, what's the different? help?
incomplete. ....SE for data set 1 .....mi thatha calculate chesthada ....😈😈😈
How can I find a published paper with error in their statistics?
I have a question: Do you also use the 1 or 2 sigma notation for standard errors or only for standard deviations?
Man yo good,more videos please ,let's say like confidence interval
And this is how you render the educational institutes obsolete.
Thank you.
