I have a questions as to when you are placing the values of population interval on the curve, shouldn't they supposed to be flipped? The value corresponding to X(0.95) is 74.55 should be on the left and vice versa for X(0.05)? I am confused and need your help.

All the videos in the series are Simple to understand and very nicely presented..Hats off to you Brandon...The only problem is I am unable to know on what order I have to see the videos. I have open a video and wait what you say in the beginning like " In the Previous Video we have seen this and that etc.". So some kind of numbering the videos will be of immense use to learners like me. Secondly I also want videos on Structural Equation Modelling..Thanks a lot for posting such wonderful videos.

I think the video would be clearer if, instead of “monthly return,” “percentage change” were used. Nevertheless, Iove these videos. I don’t know how I could learn this stuff without them.

So the Chi Square distribution only applies if the population distribution is normally distributed, correct? If the monthly returns on stocks did not follow a normal distribution, we would need to use a different method to calculate the confidence interval?

Hi Brandon .. excellent videos.. i would like to check if you would have any videos on to statistically targets for a project. This will be useful to understand. Thank you again n keep up the gr8 work.

if the population from which we are drawing samples is not normal population, will the sample variance still follow chi-square distribution?

The chi-squared curve is described as “asymptotic” because it never touches the x axis. I submit that it is a horizontal asymptote. The nature of an asymptote is that it approaches, but never touches, a specific line.

Very good video (as with the others I have watched of yours). I am a bit confused about your example with the GE and Apple stocks. You say that the Apple stock has a higher variance, but isn't it true that it is not statistically significantly higher (at least with the initial sample size), since the two confidence intervals overlap?

If the Chi-Squared distribution is not symmetric, why is the 5% p-value divided into 2 equal parts?
@cococnk388
Жыл бұрын
Because what will make it different is the critical values (chi square critical values) ... the critical values will not be the same ... so accounting for its skewed shaped (non symmetric).

Yiqing Wang Hello! Not exactly clear about your question, but the sample mean is just the average of the sample. However in general, variance decreases as the sample size increases.

***** thanks for your prompt reply. Sorry for the confusion. @ 32:07, WHEN n=12, GE s^2 = 25.89, my question is that as N changes, should S^2 also change, or it is just an assumption that it stays the same? Thanks you!

Yiqing Wang Ahh yes! OK. In this section we were holding s^2 constant to show the effects of sample size on the interval. So for the sake of learning about the effect of sample size we held s^2 constant. Hope that helps!
