SPSS Statistics is a widely used windows based software package used for statistical analysis. Its purpose was to enable easy deployment of descriptive statistics (Cross tabulation, Frequencies, Descriptives), bivariate statistics (paired sample t-tests, independent t-tests, ANOVA, correlation) as well as inferential statistics (Linear regression, factor analysis, cluster analysis).
Originally developed by Norman H. Nice, Dale H. Bent and C. Hadlai Hull in the 1970s, the first version was designed for batch processing on mainframes and used punch cards for input. SPSS released its GUI interface, and thus its present recognizable form in SPSS Version 16.0. The group of software engineers incorporated SPSS Inc in 1975, but eventually sold the company to IBM in 2009 for $1.2 billion. The acronym stands for Statistical Package for the Social Sciences (SPSS), however the program is also used in the Health Sciences, Epidemiology, and even in Business. The program’s current release is Version 23 and Homework Help USA’s writers are quite familiar with its use, in addition to the accompanying statistical theory.
