Data Analysis with IBM SPSS Statistics

Overview of this book

SPSS Statistics is a software package used for logical batched and non-batched statistical analysis. Analytical tools such as SPSS can readily provide even a novice user with an overwhelming amount of information and a broad range of options for analyzing patterns in the data. The journey starts with installing and configuring SPSS Statistics for first use and exploring the data to understand its potential (as well as its limitations). Use the right statistical analysis technique such as regression, classification and more, and analyze your data in the best possible manner. Work with graphs and charts to visualize your findings. With this information in hand, the discovery of patterns within the data can be undertaken. Finally, the high level objective of developing predictive models that can be applied to other situations will be addressed. By the end of this book, you will have a firm understanding of the various statistical analysis techniques offered by SPSS Statistics, and be able to master its use for data analysis with ease.

Example - motor trend car data

Data was obtained from the 1974 Motor Trend magazine and consists of fuel consumption in miles per gallon (mpg) and 10 variables measuring various aspects of automobile design and performance for 32 automobiles from the 1973-74 model year. The data is publicly available in the R statistical software package and is widely featured in discussions on regression.

Our presentation draws upon the discussion by Henderson and Velleman: Henderson and Velleman (1981), Building multiple regression models interactively. Biometrics, 37, 391–411.
