How to submit a True/False Answer on ML for NURS 304
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!
+Riyancie Mathews You are most welcome!
Why is the stratified sampling a probability sampling method but the quota sampling is a non-probability method?
+kalina penkova What do you mean by "Quota sampling"? There are several methods that may be referred in that way.
This is very useful for people like me who go to school online. I appreciated this and the non-probability video!
+Jessica Pena I am glad to be of help.
Thank you for the help!
+Jessica Pena You are welcome!
You explained this topic best out of all youtubers I've seen! Thanks you!
+Busy Buddy Thanks! Too kind :)
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?
stratified with proportionate random sampling technique
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 ??
chems tid Thanks for your question. Purposive sampling is used extensively and effectively in qualitative research, but it does not provide any basis for statistical inference. The problem is that no probability argument can be developed from it. You may want to look into the literature on qualitative research to explore the idea further. If you look to the right of my video, you'll see many suggestions of videos that relate to this issue.
Thank's Roberto ... But excuse me, does the descriptive analysis be enough in this case ?!!
chems tid That depends on what goals one wants to achieve. However, descriptive analysis is all one can get from statistical data collected from a purposive sample.
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
I think that's because the function formed will no longer be a single valued function
Helpful!
well explained easy to understand thanks..
Thank you, could you please consider working through a few problems with us
