How do I indicate an FPC value to be used for the entire data set?
To indicate an FPC (finite population correction) value to be used for the entire data set, click on “Options” under the table request node of the workbook tree. You can change the default FPC value of one to whatever is required for your data set. You need to calculate the FPC value yourself outside of WesVar. To do this use the formula: 1 – (n/N), where n = the sample size and N = the population size. Remember that you need to use an FPC only if your sampling fraction is large.
