You are one of the best YouTuber in the field of data science who provide the concepts in a very simple way. Thanks for making such videos.

[AIWALABRO]

The way you explain in a short time and very informative way...I always love that🤗🤗

[dipamsarkar]

just one line i have not understood as the sample size grows variance of both sample and population comes closer then we have to divide it by n-1
why??

Thank you so much, the best video till now!

Thank you very much for your video, it was very very good at explaining. But I have one more question, If descriptive statistics do not try to generalize to a population (since there is no uncertainty in descriptive statistics), then why does the sample standard deviation try to best estimate the population mean? Yet it is still considered a descriptive statistic
