Sample Size Estimation Formula introduced by William Cochran in 1967

[@celinemary2914]

Compute for the minimum sample size using an appropriate formula. Assume that no similar study has been previously done and that the level of variability is unknown. Use 2% level of precision and 90% level of confidence. The total population from 15 villages ranging from 100 to 350 and the total population is 3500.

Could you please suggest me whether Cochran formula can be used for the above example and please explain it to me, how it is computed.

sir paano po yung computation sa last part sa formula bakit iba yung nakukuha ko value

Hello Sir when to use po the Cocran Formula and what are the assumption for us to be able to use it?

[@mikelesterbianzon5570]

Sir what if hindi po available ang population? Pwede parij po ba gamitin ang cochran formula?

[@datascientistph]

Yes pwede. All you need to do is to tweak the formula

[@mikelesterbianzon5570]

@@datascientistph after po makuha yung sample size yun napo ang respondents sir? And cochran formula napo yung sampling method used?

[@datascientistph]

@@mikelesterbianzon5570 Hi Mike, that is correct and you can also tweak the formula depending on the purpose and the subject or composition of the sample.

Ang gulo sa last part

What specific Sir so I can further explain
