why should you take square root if there is no distance in higher dimensions ?

Haha, love your intro! :-) But at the same time I don't hear no practical use for this. For me, this is just learning stupid tricks. That's why math is so terribly boring. Or is it that you math-guys don't have any fantasy?

Sir upload more video on b.sc mathematics Thanks sir to explain such nice solution.

What are the applications of basis and dimensions

Great video

Thank you!

Good

Thank you

Great video, used it to study, your examples are much clearer than the examples in my study book!

Thank u sir

hello, how to choose the appropriate sampling method for infinite population?

I've heard cosh written or pronounced "kosh".

Collect a sample with high quality data might require a hard work. Another challenge is how to compute probabilities once we have the data. A common approach is to make inferences of the population mean, which is not so complicated because it allows to benefit from Central Limit Theorem. Another approach is to make inference about the probability of having a single event. These approaches answer to different questions, but both relevant. For the seconf, one example is seen in dunamath.com/homeUPC.aspx

Mr. I need to know what are the uses of probability and non probability sampling

Well explained!Thank you!

great video - subscribed!

thanq very much sir, this video saved me in my exam.

Am I correct to assume that with the integral from a to b that appears at 8:39, a is to represent S1, and b is to represent S2? Is there situations where these change, such as where we set the datum?

that was so wonderful and simple to understand... thank u so much

please can u give me an exampl about quota sammling?

too quick sir TT TT

so far this is the best video i have seen. thanks

I love you

lovely! thank you :)

I just wanted to thank you for all the video

This was very lucid and helpful. Many thanks for the upload.

Great videos! I found myself chuckling throughout. Thanks for posting

4:15 "an orthogonal matrix matrix" :)

Thanks for a great video!

Why is the stratified sampling a probability sampling method but the quota sampling is a non-probability method?

This is very useful for people like me who go to school online. I appreciated this and the non-probability video!

Thank you for the help!

You explained this topic best out of all youtubers I've seen! Thanks you!

يعطيك ألف عافية .. و شكراً لك ..

Hi sir roberto, i want to ask some help from you for my academic research study....the respondents of my study will be all the first year college students which my school has 6 departments....i got a total 1096 respondents....i am confused on what sample technique that i will use since there are some departments only has 96 students over all (adding all subdepartments), there is one department that only has 16 first year students too.....what best sampling technique should i use for my study sir?

Great stuff Bro

thank u sir:)

Thank you. It's very clear and it helped me a lot!

Hi, thank's mr.Roberto Which inferential analysis could we apply in case we choose a purposive asmple please ??

Fantastic video, Roberto; it really helped me out! Thanks for making it.

Sooo helpful....thnx for uploading !!

Thank you so much. I was lost.

Great work! Thanks :)

refer to problem of cable between 2 poles-- pls explain how to plug values in y= cosh u -- thank u sir

sir --- u r lecture is very clear-- i do not under stand why domain of inverse functions is restricted to positive values-- thank u sir

Helpful!

well explained easy to understand thanks..

Thank you, could you please consider working through a few problems with us
