SPSS Power Extension for SPSS Statistics

By Douglas Stauber posted Mon January 30, 2017 06:11 PM

  
Today we're excited to announce a new free extension for SPSS Statistics: Stats Power. Stats Power calculates power and related statistics for a variety of tests including t-tests, proportion tests, ANOVA, correlation, chi-squared, and linear models. This free extension, based on R, recreates much of functionality previously found in SPSS SamplePower.

If not working, please install the package Pwr directly open R
Packages >> Install Packages >> Chooser Server >> Look for Pwr
Then open Statistics (that has R essentials + R), it should work.

Setting up your machine to run extensions, for example installing R and R Essentials, does require admin privileges. However, installing each individual extension does not require any special privileges.

Does installing SPSS extensions require admin privileges to the computer or are extensions a per-user option that each user of a computer can install for themselves without IT support?
