Complex Samples Ratios
Some of theconfide nce intervals do not overlap; thus, you can conclude that the ratios for the
Westerncounty are higher than the ratios for the Northern and Southern counties.
Finally,as a more objecti ve measure, note that the significance values of thette sts for the
Westernand Southern counties are less than 0.05. Thus, you can conclude that the ratio for
the Westerncounty is greater than 1.3 and the ratio for the Southern county is less than 1.3.
Summary
Using the Complex SamplesRatios procedure, you have obtained various statistics for the ratios
ofCur rentvalue to Value at last appraisal. Theresults suggest that there may be certain inequities
in the assessment of property taxes from county to county,namely:
The ratios for the Westerncounty are high, indicating that their records are not as up-to-date
as other counties with respect to the appreciation of property values. Property taxes are
probably too low in this county.
The ratios for theSouthern county are low, indicating that their records are more up-to-date
than the other countieswith respect to the appreciation of property values. Propertytaxes are
probably too high in this county.
The ratios for the Southern countyare lower than those of the Western county but are still
within the objective goalof 1.3.
Resources used to track property values in the Southern county will be reassigned to the Western
county to bringthese counties’ ratios in line with the others and with the goal of 1.3.

The Complex Samples Ratios procedureis a useful tool for obtaining univariate descriptive
statisticsof the ratioof scale measures for observations obtained via a complex sampling design.
The Complex Samples Sampling Wizard is used to specify complex sampling design
specifications andobtain a sample. The sampling plan file created by the Sampling Wizard
contains a default analysisplan and can be specified in the Plan dialog box when you are
analyzing the sample obtainedaccording to that plan.
The Complex Samples Analysis Preparation Wizardis used to set analysis specifications for
an existing complex sample. The analysis plan file created by the Sampling Wizard can be
