Descriptive Statistics & Cross Tabulation
Introduction
Several procedures are available for tabulating and
summarizing your data. The frequency table procedure provides tabulation
of single variables. The cross tabulation procedure provides tabulation
of two variables into two-way tables. The descriptive tables procedure
computes summary statistics (means, median, standard deviations, etc.)
according to up to eight breakdown variables. All of these procedures
provide numeric and graphic reports. A specialized appraisal ratio
module provides reports for mass appraisal.

Accuracy
We at NCSS have put a
great deal of effort into finding the most
accurate algorithms possible. The programs have
been tested and verified over and over, both by
us and by our customers. Each routine has been
verified against textbooks, journal articles,
and, where possible, other software. NCSS is one
of the most accurate statistical analysis
programs available. NCSS calculates with
seventeen-digit, double-precision accuracy. |
