Formula for Sample Size
Different formula than MICS2000
MICS2005 formula emphasizes relative margin of error* instead of 5% absolute error (high coverage indicator) or 3% for low coverage indicator.
Does not depend on high or low coverage
* The Relative Margin of Error is the percentage of tolerable difference that the estimated proportion can differ from its true value with a given confidence level. It determines the relative length of the confidence interval.
