Spss Version 18 _top_

Originally released in the summer of 2009, (often referred to as SPSS Statistics 18 ) represents a significant transitional point in the history of this widely used statistical software package. At the time of its release, it was the first major version following SPSS Inc.’s acquisition by IBM in 2009. Consequently, while the software still carried the “SPSS” name prominently, it also marked the beginning of the product’s gradual rebranding to IBM SPSS Statistics .
