Measures of Dispersion (Ungrouped Data) | Basic Statistics

Simple and clear explanation on how to find the range, variance, and standard deviation of an ungrouped data.

Thank you so very much sir m starting to love maths you teach so very well keep on transforming lives 😊 ❤

[@leniejanetabuso6558]

Thank youuuuu, it helps me a lot. It was easy to understand, keep it up Sir. Be safe and healthy as well. Godbless💗

Thank you for watching my vid 😅

Thank you so much sir, I was able to answer my modules

[@annamarieroxas2769]

Sir what if the given set of data's was plenty or I mean the numbers were repeated. How can we solve for it. Thank you for the response.

[@PinoyMathematician]

Same solution as long as it's ungrouped.

Thank you po sir ang galing niyo magturo Hindi Gaya Ng iba na kinakausap Lang ang sarili

Thank you sa pag appreciate ng vid ko. 💗

Sir can you have a tutorial on how to get the variance of a data

[@ernestMdube]

Well done Sir!!

[@ma.rhianyanoc7740]

Thank you sir it helps me so much!!

[@owusujoseph2757]

Why we use sample variance and sample standard deviation instead of variance and standard deviation ??

[@PinoyMathematician]

if you only get the data from the sample. not from the whole population.

[@owusujoseph2757]

@@PinoyMathematician so will it be stated in the questions that is population or not ??

[@PinoyMathematician]

yes. it must mention a "sample" or a "population". Otherwise, you assume it to be a sample.

Thank u sir for uploading an video in English. 🥰

[@OllorJohn-kr7so]

Please sir try to add sample standard deviation and sample variance

Nice one sir Ralph!

bobo ako sa math tapos ito pinapareport sakin sa weds huhu why you do this to me mam 😥😥😥☹☹☹
wala po ba tagalog nito para lalo maintindihan ...

[@mycgld]

good day, sir. what is the difference between the ungrouped and grouped data in the measures of dispersion?

[@PinoyMathematician]

The given in ungrouped data is not in table form.

[@mycgld]

@@PinoyMathematician Okay, Sir. Thank you so much for the response. God bless po. ❤️

[@GhulamMustafa-zv9qp]

Very nice sir

[@JinHee.]

If there's a repeated number it will still written both or just one?

[@PinoyMathematician]

write both

[@PinoyMathematician]

write both

[@torreonjodel8553]

Eh pano naman po kapag 50 yung given data?

[@nikoletangela]

thank you po

[@osamaathman229]

how come in some books the formula for varince has it denomenetor as (n) and not (n-1)

[@PinoyMathematician]

You use n if the data is from population, you use n-1 if the data is from a sample.

[@osamaathman229]

@@PinoyMathematician suppose the data is from a social survey in which the purpose was to was to establish IQ of students in a given area. would it be population or sample data

[@PinoyMathematician]

@@osamaathman229 it's sample, since it is not specified. As long as it's not stated in the given, it is assumed to be a sample only.

[@hashtagcoding5809]

@@PinoyMathematician is there any other formula that changes when the data is from population?

[@lakmalrmck]

thx sir

[@seyee4]

Thank you

[@chidimmacathy374]

Fine the mean and deviation of 1 3 5 7 9 and 10

[@myrlyvergaracabrera484]

thanks!

[@brnlln3503]

The formula is wrong bro
