    Thank you for your clear explanation about infinite and finite methods. I want to know what type of research we are using this method, it is possible to use it for household food insecurity access scale, access prevalence, and food consumption score.

Anyway, if it is not possible to conduct census and if it is required to take representative sample so that you can conclude about the population. You can use either formula as per the characteristics of your target population.

    Thanks for the lesson. But what if we use the simplified corrected sample size determination formula. Which is nf=n/(1+n/N), almost the result is the same,842.9~843?

      Yemane formula is proper for determining the sample size at sample unit level.

    Dear Solomon,
    In a cross sectional survey with known populations, N=117
    which sample size calculations formula can I use to determine my sample size apart from Slovin formula and modified Cochran formula ?

    • @SolomonGetachew
      @SolomonGetachew  Рік тому +1

      The total population is so small that is 117. Thus, no need to take sample. Instead, conduct censes.

      Thank you for the prompt response. And subscribed!
      Certainly, Census would better suit given the sample size. However, I was advised to rather look into sampling techniques and formulas. That is why I ask you about the formulas. Is there any books that you’d recommend on this?

    I assume that population size is unknown/ infinite, therefore I plan to use Cochrane Formula- which gives a sample size of 384, for this study, at 95% confidence interval, 50% degree of variability, 5% as margin of error. All my questions are on Likert 5 point scale (Interval data). Is that appropriate to be used?.
