45 C.F.R. § 1356 app C to Part 1356
Current through March 31, 2024
1. Using Finite Population Correction
The Finite Population Correction (FPC) is applied when the sample is drawn from a population of one to 5,000 youth, because the sample is more than five percent of the population.
* (Py)(Pn), an estimate of the percent of responses to a dichotomous variable, is (.50)(.50) for the most conservative estimate.
* Acceptable level of error = .05 (results are plus or minus five percentage points from the actual score)
* Z = 1.645 (90 percent confidence interval)
* N = number of youth from whom the sample is being drawn
2. Not Using Finite Population Correction
The FPC is not applied when the sample is drawn from a population of over 5,000 youth.
