Sample size calculation

Calculating sample size under required precision: intra-couple analysis

The tool calculates sample sizes, i.e., the number of households required for intra-couple analysis. Please enter values for all the necessary parameters if differ from the default value shown and follow instructions on the screen to estimate the number of households need to be approached in a household survey.
