Derivation of the formula for finding the Margin of Error n=N/(1+Ne^2) n(1+Ne^2)=N 1+Ne^2= N/n Ne^2= (N/n)-1 e^2= [(N/n)-1]/N e= sqrt{[(N/n)-1]/N} You may counter check my formula by providing some values. To reiterate, you may or may not distribute the "n" There will be some instances that there will be two or more formulas that will give the same value e.g. Ordinary Annuity. You may try to google it. There are three formulas or may be more if there is. If you are in doubt, you may send me an Email.
Thank you for your comment. Please take note that you should do it in the calculator continuously. Do not round it off at the middle of the computation. Also, you may also notice the bar at the top of 0.66, it means it is a repeating decimal, which I have stated in the video. :)
Galing siya sa formula ng sample size Slovin's formula for sample size: n= N/(1+Ne^2) Derive natin para makuha si "e" n(1+Ne^2)=N (1+Ne^2)=N/n Ne^2=(N/n)-1 e^2= [(N/n)-1]/N e= sqrt{[(N/n)-1]/N}
determine the proportion of a population of 4000 will make your research work scientific in terms of sampling? used slovins formula at 0.05 level of significance. can you help me answering this. ty po
Hi there. Kaya ganyan sagot kasi mapapansin mo na may bar sa taas ng 6 ibig sabihin repeating decimal siya So, instead na ganito lang 25.66, it is like this 25.666666666666666666666666666 and so on. So, kapag nilagay mo siya sa calculator, magiging sagot ay 0.00320833333333333333333333333333333333 and so on.
The margin of error is a guide on how accurate your answer will be. The lower the margin error, the more accurate it will be. And yes, it will affect the sample size also, if you will make it higher like 10%, it will have a lower sample size.
Actually, I am struggling on getting my target sample size response. I already extended my data collection still I have very low survey response that is why I wanted to increase to 10℅ my margin of error to decrease the number of sample size.
@@reymanangan3196 The ideal margin of error is until 10% only. Beyond that is somewhat not acceptable, and it will the data will not be reliable anymore.
For clarification lang. Mali po yung formula. Mali po yung checking pag ganan yung formula. Dapat po dinestribute nyo po yung n sa 1+Ne^2, then magiging n+Nne^2=N tapos ililipat yung n from left side to the right side para ma-isolate yung e so magiging Nne^2=N-n, then divide both side by Nn para maiwan yung e, so magiging e^2=N-n/Nn. Since naka squared pa yung margin of error kelangan natin i-square both side para macancel sya. So the formula for the margin of error is e=√N-n/Nn. Try nyo pong I-compare yung formula by executing both formulas tas check nyo nalang kung alin yung match dun sa sample size.. hehehe
Hi upon checking both of our formulas are correct. You may or may not distribute iyong "n" n=N/(1+Ne^2) n(1+Ne^2)=N 1+Ne^2= N/n Ne^2= (N/n)-1 e^2= [(N/n)-1]/N e= sqrt{[(N/n)-1]/N} You may counter check my formula by providing some values. To reiterate, you may or may not distribute the "n" Lastly, both of our formulas are correct. There will be some instances that there will be two or more formulas that will give the same value e.g. Ordinary Annuity. You may try to google it. There are three formulas or may be more if there is. If you are in doubt, you may send me an Email. Anyways, thank you for watching my video.
Good evening. Ang turo Po samin sa pagkuha ng margin of error is, level of confidence minus 100% then the answer will be the margin of error. Is that correct?
Kapag confidence level binigay, makukuha mo na iyong margin of error. For example: ...with a 95% confidence level, edi ang margin of error mo ay 5% or 0.05
Sir Sabi mo SA video na "confidence level is the same as margin of error" bakit 95% po ang sagot 5% po dpat o may Mali Lang po na SA statement nyo? Thanks po
Huwag po kayo magroround off kapag nasa kalagitnaan ng solution. Dapat dare daretso siyan sa calculator Kung mapapansin nyo po, may bar sa taas ng 0.66, ibig sabihin repeating decimal siya. So ang ilalagay po sa calcu ay 25.666666666666666666666666666666 tapos dun niyo po siya idivide ng 8000
Sir tanong lang. Haha ang goal ko kasi, mahanap ang sample size ng population kong 125. However, hindi ko alam ang margin of error na kailangan para makuha ang sample size gamin ang slovin formula. Paano po yun? Haha
@@mathandlanguagebyjamesjuni sa research po kasi ito sir. May 159 po kaming population from 4 sections ng grade 9 students. So, di naman po kering interbyuhin lahat yon kaya need sana makuha sample size noong 159. Tas nakita ko po ung slovin formula, kaso di ko naman po alam pako kunin ang margin of error since needed siya sa slovin. Ty po
Pero sir if I used the margin of error formula: given N = 400, n=50 Equal to 13% po. So if I were to use the formula to find the confidence coefficient which is 100% - 13% = 87% Which is ang given po is 95% confidence coefficient. Is it OK, hnd po nag match? Salamat po
