Population vs Sample in Statistics

In this playlist we will be discussing about the Statistics concepts in Machine Learning and Deep Learning. Initially we will understand the basic difference between the Population and Sample. We will also understand Population Mean and Sample Mean

Really appreciate your efforts. One thing which I want to raise out that statement "population mean is always greater than sample mean" is not correct. It depends how sampling has been done. Say population set is {1, 2, 5, 3, 7, 8} and sample set is {5, 7, 8} as subset of population set. So here mean of sample is greater than mean of population.

Nice work! Appreciate your efforts 😊 Kindly add more videos to the stats session. Pls complete the series and also touch upon maths behind each algos.

Thanks for the video krish ji post many videos on context aware recommendation systems this is my research topic thank you for your great support ur videos are precious u have a long way to go u are my inspiration love u lot🙏🙏🙏👏👏👏👍👍👍👍

Hi Sir, Come over Your video and found it really valuable in terms of clean and simple explanation. Keep to share You knowledge in this way. Will check the other You videos. If other videos will be so good, You will get my subscription.
Thanks,

Hi @krish Naik, Your efforts in this complete DS/ML field are remarkable for the people with fewer resources.
However, I may have found a mistake in this video or maybe it's just that I'm not thinking it right!
In the end, you state that population mean will always be greater than the sample mean, I don't think this is a must hold for every sample. I mean wouldn't it depend on the sample we have taken?
let's say we have a population of 6 people and heights are as follows- 6, 6, 6, 3, 3, 3(in ft), Now if our sample is the first three people then the sample mean will be 6 and the population mean will always be somewhere around 4, right?

hello, your all videos are very good and I appreciate your efforts, but I have a request from you .Can you make one video of any one algorithms where we implement stats and these test like(t test, z test, anova) we used and how to get analysis from those stats and test.
Thanks in advance

Hello sir You explained topics very clearly with real time examples where we can get the idea of applying these stats in real time, but there is one concern about where can I get the videos of Population Distribution, Sample Distribution, Sampling Distribution, concept fo skewness, variance, standard deviation and some of the topics you didn't cove

[sushnandy]

Your lecture is very good and easy to understood.Plz improve sound quality on this video

[anilkumarsahu]

Video is really appreciable ..
Sir audio quality improve kariye please.

[shivaprasadshirawar]

I decided to enter into data science field by watching your videos only Sir. The content and your efforts are really amazing.BTW Are you from karnataka sir?. I'm from karnataka

[naveenvinayak]

Really appreciate your efforts,
sir can you make a video about P-value and T-value

[karimkhan]

Hello Sir, Your videos are very nice. please create a calculus series. Thank you Sir .

[justdoit]

Hi krish, i was going through statistics in machine learning playlist in couple of videos you mention in our previous videos we already mentioned about some content. is the playlist contains all the videos in sequence. for ex. after covariance in statistics in the next video you talk about we already discussed about TPR FPR confusion matrix which was not discussed in the playlist sequence videos earlier. like way you mention about snd in log normal distribution as we already discussed. did i missed the sequence of videos?

[msarkar]

Hello, dear Krish, Please create and upload on statistics that required Data science. Because your 31 viedos is not enough for data science according to your mentioned syllabus . So please please

[aleenakotadiya]

How do you select sample from the population? Is it done randomly or are their any specific criteria to it?

[abrahamowos]

Lol, Krish your writing has gotten a lot better as compared to your recent videos. Thank you for all you do.

[rickypraveen]

hai krish i regularly watching your videos, i have doubt about data science is there any chance to handle non maths students can do a data science are not.

[krishnavamsi]

Hi sir, In the last part of video you said sample mean is smaller than population mean, but it need not be the case right, if the sample selected has more values higher than population mean? Or is my understanding wrong?
