Confidence levels in confidence intervals

Confidence levels such as 90%, 95% and 99% can be confusing. This short video concentrates on the impact of the level of confidence on the width of the confidence interval.

Fairly underrated channel. Dr Nic makes so so complex topics fairly easy to understand!!! Arguably one of the best stats channel out there. Till now before this video, I couldn't very well define Confidence Interval but now I can with ease.

Excellent explanation madam.
Keep it up you are doing excellent work.

Thanks great explanation, regarding confedince level : how do you know if a specific confedince interval contains the population parameter, if we don't know it ( after all we don't know the value of the true parameter ) ?

Hi Dr Nic, I'm confused about the "net theory". I believe that the narrower is the confidence interval, the more precise will be the values obtained from a sample, thus being generalizable to the population.

The more is the confidence level, the higher is the chances to get a precise value, right? So, why wouldn't a higher confidence level cause the interval to be narrower as well, due to a narrower interval give rise to higher accuracy in relation to the population parameter.

I find these concepts conflicting, do you mind clearing my doubt? Thank you :)

Why would we expect 95% of our C.I.'s from many different samples to contain the true population mean?

Most of these videos go too fast. Seems to be teaching someone who already has some prior understanding of these concepts but doesn’t address the needs of beginners trying to understand them.
