do i have to use variance correction in a sample for a poll can variance be corrected for each cell does variance in a survey depend on the clustering of the count? does the variance correction affect the probability distribution do variance corrections for a cell count can variance correction be used to estimate population are variances calculated by theisson distribution? why do variance corrections for counts depend on the probability distribution do the variance correction for cells depend on something other than and additional to the value of the count or the underlying cell probability? are variance corrections necessary for the measurement of population how to correct population variance can the variance for each cell be corrected why do variance estimates depend on the clustering why do variance corrections depend on clustering does poisson represent the range in the measurement do variance estimates depend on clustering and stratification which of these factors is associated with a variance correction in a multidimensional survey design? how does the variance affect the survey do variation corrections for survey design imply that the population is not distributed according to the poisson distribution? what do variance corrections for cell counts indicate?
