A statistical package is a kind of large computer program that is specialised for statistical analysis. It enables people not skilled in programming to obtain the results of standard statistical procedures and statistical significance tests.


Examples of commercial statistical packages include (in alphabetical order):

  • GenStat
  • Macanova
  • Minitab
  • SAS
  • SPSS
  • Stata
  • Statistica
  • StatView
  • Systat
  • S-PLUS

Open-source:

Almost all these are now also the titles of the software companies that produce them (and usually other software as well).


There are also a great number of freeware or shareware statistical packages, listed below in the external links page.

Carlson, Software for Statistical Analysis of Sample Survey Data (4341 words)
Statistical methods for estimating population parameters and their associated variances are based on assumptions about the characteristics and underlying distribution of the observations.
Packages should have the capacity to handle nonstandard designs, or provide guidance in the documentation as to the most appropriate design to specify in these circumstances and what the consequences are (such as an overestimate of the variance).
Depending on the specialized package and the estimates desired, it may be necessary to then take the output from the specialized package and carry out further data manipulation in the original general-purpose (or yet another) statistical package to obtain the needed estimates.
