INTRODUCTION TO SPSS

What is IBM SPSS Statistics?

IBM SPSS Statistics, formerly known as the Statistical Package for the Social Sciences (SPSS), is a robust software program used for managing, analyzing, and interpreting quantitative data. For over three decades, it has been a vital tool for researchers, analysts, and academic institutions around the world. Originally developed by three Stanford University Ph.D. students—Norman H. Nie, C. Hadlai ‘Tex’ Hull, and Dale H. Bent—SPSS was created to make statistical analysis easier and more efficient for social science research. In 1975, the founders established SPSS Inc. to commercialize the product. In 2009, IBM acquired SPSS, fully integrating it into the IBM Business Analytics Software portfolio, where it continues to serve as one of the most widely used tools for data analysis and decision-making.

Brief Corporate History and Evolution of SPSS

Background

The evolution of SPSS Inc. as a company has been guided by two central themes:

1. SPSS technology simplified complex analytical processes through improved usability and data access, enabling more individuals to apply quantitative techniques in decision-making.
2. The company’s focus has always been on analyzing human-related data—opinions, attitudes, and behaviors.

These themes underpin the company’s mission to promote the widespread use of data in decision-making. SPSS’s success has stemmed from its ability to demonstrate the real-world benefits of data-driven analysis. The founders believed that analyzing data and integrating results into decision-making processes leads to better, more informed outcomes.

The Origins of SPSS

In 1968, Norman H. Nie, C. Hadlai (Tex) Hull, and Dale H. Bent developed SPSS at Stanford University. Their goal was to create a software system capable of converting raw data into actionable insights using statistical techniques. Nie, a social scientist, defined the project’s requirements; Bent, a doctoral student in operations research, designed the system’s file structure; and Hull, a business administration graduate, wrote the software code. Originally intended for use within Stanford, the software soon attracted widespread attention across American universities due to its practicality.

The first SPSS User’s Manual, published by McGraw-Hill in 1970, contributed to its rapid adoption. As its popularity grew, the U.S. Internal Revenue Service classified SPSS as a commercial entity in 1971, prompting the establishment of SPSS Inc. in 1975. Despite limited funding, the founders managed to make SPSS compatible with various mainframe computer systems, solidifying its presence in the academic and research sectors.

Expansion and Growth

During the 1970s and 1980s, SPSS expanded beyond academia into government and commercial industries. Organizations such as NASA, the U.S. Forest Service, and corporations like Procter & Gamble and Anheuser-Busch used SPSS to analyze operational and marketing data. The company continued to innovate by introducing the first mainframe statistical software for personal computers in the mid-1980s and launching a Windows-compatible version in 1992.

Leadership and Modern Development

In 1992, Norman Nie stepped down from daily operations, appointing Jack Noonan as President and CEO while remaining Chairman of the Board. Under Noonan’s leadership, SPSS Inc. grew further through strategic acquisitions, expanding its product line to include tools for data mining, web analytics, text mining, and online analytical processing (OLAP). These enhancements positioned SPSS as a leader in the field of business analytics and data-driven decision-making.

By the time IBM acquired SPSS in 2009, the company had become a global powerhouse in statistical analysis software, serving government agencies, academic institutions, and corporations worldwide. Today, IBM SPSS enables users to learn from past data, understand current trends, and forecast future outcomes to support evidence-based decisions.
