FLORIDA DEPARTMENT OF REVENUE AID AND ASSISTANCE WORKSHOP
JANUARY 31 – FEBRUARY 1, 2017
AID AND ASSISTANCE WORKSHOP
TIME TREND ANALYSIS
Description
Property Tax Oversight offers this workshop as aid & assistance for property appraisers and their
staff. The department has been using a time trended sales ratio methodology for analyzing as-
sessment rolls since 2011. This methodology increases the statistical reliability and accuracy of
ratio studies, and counties can use it to test rolls before submitting them to the department. Dur-
ing the workshop, instructors will demonstrate the methodology using real data.
This workshop will provide:
an introduction to the fundamentals and principles of adjusting sales for market conditions.
specific information about DOR’s sales ratio time trending method.
criteria for determining the inclusion or exclusion of sales in the analysis.
tools to determine the most appropriate analysis based on the data.
Day 1 will be lecture, and day 2 will be hands-on time trending exercises using Excel and pre-
pared sales datasets. Participants should bring a laptop with MS Excel (version 2010 and above)
already loaded, the Analysis Tool Pack and the Analysis Tool Pack - VBA enabled. Excel macros,
SPSS syntax, and data sets will be available at registration check-in. Day 2 will also include an
overview of the SPSS syntax, which counties can use instead of Excel for larger datasets or
more complex analyses.
Participant Information
Participants should bring a laptop that fits the specifications above, laptop power cord, extension
cord, paper, writing utensil(s), and a jacket or sweater.
