SPSS is a statistical analysis software package that allows a wide range of manipulations and procedures to be performed on datasets. Unfortunately, one procedure that is notably absent is the geometric mean. This is a central tendency statistic used when a dataset is skewed or has been altered by some relative function. Despite being missing from SPSS, the geometric mean can be calculated using a combination of SPSS’s “Compute Variable” function, and a scientific calculator found on most computer operating systems for free.
