Medyo nalilito ako sa formula ng standard deviation. Based sa Gillesania, over n lng yung formula, pero sa Besavilla over n-1. Na try ko dn sa calculator yung no. 1, 0.6745(SD or xn)÷sqrt(n) - - - Same ito sa vid mo, pero yung ans is 0.02590. Pero pag 0.6745(SD or xn)÷sqrt(n-1) yung ans is 0.0299 which is correct at yung expression is same sa formula ng probable error of the mean na over dn sa n(n-1). Tinry ko baliktarin, 0.6745(Sample SD or xn-1)÷sqrt(n) yung ans is 0.299. Indi ko gets bat mali yung ans ko if yung 0.6745(SD)÷sqrt(n) (Same sa vid) ginamit ko. Sa no. 2 dn, since standard deviation, so x(sigma)n , yung ans is 0.0768 pero kng sample standard deviation nmn x(sigma) n-1,yung ans is 0.0889. Indi ko dn d2 gets bat standard deviation yung reqd pero bat nsa sample standard deviation yung correct ans. Also, poh yung ginamit mo is sx which is sample standard deviation. Meaning to say automatic na sample SD talaga yun bsta sa surveying? Canon f789sga at casio 991es pala gamit ko poh. Baka mka elaborate ka poh d2 engr. Especially yung formula sa Besavilla book na over n-1 yung SD pero sa Gillesania over n lng yung SD. Thank you in advance engr.
ah maam based po sa solution nyo yung tinutukoy po nyong probable error ay yung probable error of the mean (with /√n). pero meron din po dibang probable error of any measurements (just 0.6745 Sx/ pano po malalaman kung alin sa dalawa yung hinahanap sa pag sinabing provable error lang at hindi na specified problem?
thank you for this☺️ di ko na kasi alam kung ano gagawin ko sa problem😅 sakto exact question pa dito hehe
Keep posting po, very helpful❤!
Ganda ng content mo lodi sobra ako si Team Charles🏆
Thank you po 🙂
Wow ang galing naman.
Wow, more videos po Engineer 🥺
What is the value 0.6745 used for ?
Hi! Sorry for the late response, 0.6745 is the constant value for the formula of the probable of error.
Very informative
Thank you, helpful sobra!
Welcome, future engineer ❤️
Hello po anong book po yan
thank you!

Good Day Sir. Kindly message me thru my facebook page, so I can discuss it to you
ah maam based po sa solution nyo yung tinutukoy po nyong probable error ay yung probable error of the mean (with /√n).
pero meron din po dibang probable error of any measurements (just 0.6745 Sx/
pano po malalaman kung alin sa dalawa yung hinahanap sa pag sinabing provable error lang at hindi na specified problem?
lakas! ty sir
