Complex Samples Descriptives
Summaries. This group allows you to request estimates of the means and sums of the measure
variables. Additionally, you can request ttests of the estimates against a specified value.
Statistics. This group produces statistics associated with the mean or sum.
Standarderror. The standard error of the estimate.
Confidenceinterval. Aconfidence interval for the estimate, using thespecified level.
Coefficientof variation. The ratio of thestandard error of the estimate to the estimate.
Unweightedcount. The number of units used to compute the estimate.
Populationsize. The estimated number of units in the population.
Designeffect. The ratio of the variance of the estimateto the variance obtained by assuming
that the sample is a simple randomsample. This is a measure of the effect of specifying a
complex design, where values further from 1 indicate greater effects.
Squareroot of design effect. This is a measure of the effect of specifying a complex design,
where values further from 1 indicate greater effects.

Statisticsfor Measure Variables. Thisgroup determines which cases are used in the analysis.
Useall available data. Missingvalues are determined on a variable-by-variable basis, thus the
cases used to compute statistics may varyacross measure variables.
Ensureconsistent case base. Missing values are determined across all variables, thus the
cases used to compute statistics are consistent.
CategoricalDesign Variables. This group determines whether user-missing values are valid
or invalid.
