Multiple imputation is a technique that allows analysts to incorporate the extra variability due to imputation into their analyses. This is accomplished by analyzing each of the five completed data sets separately using methods and software that are appropriate for survey data, and then combining the estimates and standard errors using the combining rules described in Section 2.
The extra variability due to imputation cannot be incorporated by simply analyzing a single completed data set as if the imputed values were true values. Moreover, analysts should not create a single completed data set using the average of the five sets of imputed values.
