What is finite correction factor?
The finite population correction (fpc) factor is used to adjust a variance estimate for an estimated mean or total, so that this variance only applies to the portion of the population that is not in the sample.
Why the finite population correction factor FPC should be used?
The Finite Population Correction Factor (FPC) is used when you sample without replacement from more than 5% of a finite population. It’s needed because under these circumstances, the Central Limit Theorem doesn’t hold and the standard error of the estimate (e.g. the mean or proportion) will be too big.
Why do we make a continuity correction?
A continuity correction factor is used when you use a continuous probability distribution to approximate a discrete probability distribution. For example, when you want to use the normal to approximate a binomial. Watch the video for an example: q = probability the event doesn’t happen (100% – p).
How is finite population correction ( FPC ) factor used?
The finite population correction (fpc) factor is used to adjust a variance estimate for an estimated mean or total, so that this variance only applies to the portion of the population that is not in the sample. That is, variance is estimated from the sample, but through the fpc it is used to assess…

Can a standard error be computed from an infinite population?
Most formulas used to compute standard errors are based on the idea that (1) samples are selected with replacement or that (2) samples are selected from an infinite population. In actual research, neither of these ideas hold true.
