Complex Samples Ratios
The Complex Samples Ratios proceduredisplays univariate summary statistics for ratios of
variables. Optionally, you can request statisticsby subgroups, defined by one or more categorical
variables.
Example. Using the Complex Samples Ratios procedure, you can obtaindescriptive statistics for
the ratio of currentproperty value to last assessed value, based on the results of a statewide survey
carried out according to a complexd esign andwith an approp riate analysis plan for the data.
Statistics. The procedure produces ratio estimates, ttests, standard errors, confidence intervals,
coefficientsof variation, unweighted counts, population sizes, design effects, and square roots of
design effects.
Data. Numerators and denominators shouldbe positive-valued scal e variables. Subpopulation
variables can be string or numeric butshould be categorical.
Assumptions. The cases in the data file represent a sample from a complex design that should
be analyzed according to the specifications in the file selected in the Complex Samples Plan
dialog box.
