The thing I hate about professors is that they are somehow able to always explain the most simplest of concepts in the most confusing of terms. Thank you for this clear explanation.

Honestly, I think they do this because some of them want to feel important. Einstein himself said, "If you can't explain (the subject) simply... then you don't know it well enough yourself..."

Miss, I'm literally about to take exam on this material...😭😭 You explain this much better than my professor. Thank you very much for this, I now understand that the confidence level correlate directly with the Z-level which I can use to calculate the confidence interval. From the bottom of my heart, I sincerely thank you😭😭

Thanks for the video, but I think i've spotted a small mistake, since you are using the sample sd you shold base your confidence interval on the t-distribution, not on the nomal distribution, exept, when your sample size is large, then z and t values are similar.

It is more usual to call the sample mean "x bar". It is also more usual, when calculating confidence intervals of means from a normally distributed population, to use the student-t critical value rather than the Z, particularly when you are using the sample std deviation. The formula you are showing here would either be an approximate confidence interval or a large sample confidence interval for the population mean. Also, be very careful when interpreting confidence intervals. In classical (frequentist) statistics, it is not true to say "the population mean will fall within the confidence interval 95% of the time". In classical statistics we assume population parameters are fixed, unknown constants, so apportioning probability to their value is incorrect. The confidence interval is the random quantity here. If you want to correctly interpret a 95% frequentist CI, you need to acknowledge it is the CI that varies randomly from sample to sample and say something like "if 100 samples were taken from this population, and a 95% confidence interval (for the mean) was calculated each time, 95 of these intervals would contain the true population parameter (mean)." If you want to interpret interval estimates in the way you have described in your video, you need to become Bayesian and talk about credible intervals.

If you don’t know the value of the population mean, is it possible to know *for* *certain* if the confidence interval contains the population mean?
@datatab
2 жыл бұрын
Hi many thanks for your question! No, that is exactly the purpose of the confidence interval. For example, if you take the 95% confidence interval, it is 95% likely that the mean of the population lies within the confidence interval and 5% likely that it does not lie within the confidence interval. Since we do not know the true value, we can only estimate and give a probability.

Could you explain the s/sqrt(n) part. I guess that std. Deviation equals the sqrt(variance divided by n). So why is there yet another division with n when you calculate the C.I.?
@datatab
2 жыл бұрын
If you divide by sqrt(n), you calculate the standard deviation of the mean (Also called standard error), that is, how much the mean varies. Without sqrt(n) you calculate how much the whole data varies. But we want to know in which range the mean fluctuates so wie use s/sqrt(n). Regards Hannah
