Problems with Slovin’s Formula: Slovin’s formula gives you a ballpark figure to work with. However, this non-parametric formula lacks mathematical rigor (Ryan, 2013). For example, there is no way to calculate statistical power (which tells you how likely your study distinguishes an actual effect from one of chance). It’s unclear from any reference texts exactly what the “error tolerance” is (a mean, or perhaps a proportion?). Some texts call the error tolerance a “tolerance margin of error” (e.g. Ariola, 2006), although it seems to be unrelated to the margin of error used in traditional hypothesis tests. The Margin of Error in that sense is the error associated with a result (for example, you could say 62% of people voted for so and so with a 3% margin of error). From the context, it’s almost certainly another name for the alpha level. The lack of precision with wording is yet another reason the formula has a poor reputation in academia. But perhaps the biggest reason that the formula isn’t widely accepted is that is seems to have materialized out of nowhere. In fact, no one seems to even know who Slovin is, or even if he existed at all. Source: www.statisticshowto.com/how-to-use-slovins-formula/
Since most of the audience here are students, much better if this were written in a more comprehensive way. What's the point of using too much technical terms if they don't understand em?
Thank you sir for simple and clear explanation. I'm binge watching all your videos for Statistics. I'm a Psychology Graduate and will have my board exam for Psychometrician this June and I forgot Statistics. I'm looking for videos to refresh me of my statistic subject. And fortunately I found your channel. This is super helpful 🥺Thank you so much
"Pano kapag hindi alam ang total sample size? Pano gagamitin ang Slovin's formula? " Isa yan sa pinaka simpleng tanong. Madaming published articles na nagsasabi ng mga problema sa pag gamit ng slovin's formula. If you have time, pwede kayo magbasa. Madami dyan way to calculate the required sample size para sa isang study. Alam nyo ba ang Power analysis? If not, pwede kaya manood din sa RU-vid on how to calculate a minimum required sample size using Power Analysis for your study.
Correct me if I am wrong sir but I think if we follow PEMDAS the placement of the parenthesis should encompass all the denominator, not on the margin of error alone.
Ano po ang difference ng level of significance at margin of error? Sa question po kasi given that the level of significance is 0.05, and not the margin of error. Is it the same po?
hello po! what if yung given po is yung sample size (n) at margin of error (e) then population size (N) po yung hinahanap. Paano po idederive yung formula? thank you!
Hello! Ang 0.0025 at 2.5x10^-3 ay pareho lang. Sa 2.5x10^-3, dahil may -3 tayo sa taas ng 10, kailangan nating umusod ng tatlong decimal places pakaliwa. Kaya eto ay magiging 0.0025 rin.
Hello po! How po malalaman yung margin of error? We are conducting a research po kasi and need namin ng sample size so we can proceed to systematic sampling
Hello po sir question po, kung gagawin kong 10% ung margin of error ko ano pong magiging cofidence level ko? At ano pong acceptable reason bkit ginawang 10% margin of error po, hope to hear from you! Thank you po :)
