If anyone else was super confused about "n-1", apparently, it's called "bessel's corrections" and it's the due to the difference between a full population's standard deviation and a sample of the population. If it's the full population you use "n" and if it's a sample, you use "n-1".

thank you this helped

I've checked out so many and you are by far the best. I truly understand after I watch the videos. Not like others where I'm just as confused as when I began. Thx

Love Math, you're video's making it even more enjoyable to me!👍󾓦✌

Just loved it , I was trying so hard to learn this but you made it so simple for me.Thank you so much.

Thanks allot u r better than any lecturer at the university. Love u fir that ❤️❤️❤️❤️❤️

I don't actually have anything to comment, I just appreciate how well you explain things in your videos, and I've heard that commenting on videos helps

This is a great help, thanks for your videos

Thank you for explaining this so well!

thank you for your dedication

Just found your channel and I'm in deep love with it. Thank you very much for your work.

I really like your video. Thank you for making this.

Thank you man, you just helped me pass my AP bio exam

Well explained ! Thank you

Thank you as usual!

Well done!

dear our teacher thank you to give us these great tutor. I ame from ethiopia

If my sample size is small, should I do a normality test and why?

Thank you very much !

THANKS MY MAN!

Sir can u make a video tutorial about naming of coordination compounds.

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?

In the second example, the 9th minute exactly, you said the relation is that when you increase the "n" by a certain factor, the standard deviation of the sample decrease by the half of this factor. Actually the standard deviation decreases by the square root of this factor not the half, as if you try any number rather than 4 it will explain my words. Thanks

Can you please explain the 2 standard error.

Thank youuuuu🙏🙏📚

You just told about calculations but what outcome interprets.

What is the difference between standard error and standard error of mean?

Best ever

very interesting

How did you get the 3.114? I don't know how to put the sum of variance in the calculator to get the 3.114

@Tsss646

Because he divided in to 4 instead of 5. Big mistake

I am getting the standard deviation of the sample as 2.6, can someone please verify the calculation?

1) I was given with 4 values, which are considered population. Then I have made possible samples of size 2, I got total 6 samples. Now I calculated mean of these 6 samples(m1, m2, m3, m4, m5, n5). Now I was asked to find the sample error of the means how to calculate it. Can you explain it clearly 2)And are there both population standard error and sample standard error 3)And i can't get where to use sample standard deviation and population standard deviation.

Hello Can I ask Why did you come up with 3.114 I can't Get it in my Equation

Please 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.

How did you get 3.114????

Thanks u

Sir,when we get the mean value ,is it answer should be round up?(like 20.8 to 21)

@mel-ej5pr

Жыл бұрын

don't round up the mean

Isn’t it that when you have something with a negative in parenthesis and square root it, it is always positive. For example (-0.8)^2 would be 0.64, but -0.8^2 would be -0.64. In they first problem the answer was as if the numbers didn’t have parenthesis around them. I’m the proper equation should you put parenthesis around the numbers when squaring them of not?

why did you divide the sum of the variance by 4 instead of 5 in part 1 but in part 2 you divided by the whole sample size?

@apotv1

because the n-1 that's 5-1 will give you 4. N is the number of observations or the sample size. thanks

Anyone know what it means conceptually to calculate the standard error (SE) of a single sample (of sufficient sample size) if SE means the spread of many hypothetical means around a population mean? Assuming you don't know anything about the population.

Every time I need to know “why” and u tell me “why” 😂

Must it be taller though?

how you get 3.114? i calculate all that i have but the answer is wrong?
