• Introduction Part 1 PASW stands for Predictive Analytics Software. This program can be used to analyze data collected from surveys, tests, observations, etc. It can perform a variety of data analyses and presentation functions, including statistical analysis and graphical presentation of data. Among its features are modules for statistical data analysis. These include 1) descriptive statistics, such as frequencies, central tendency, plots, charts, and lists; and 2) sophisticated inferential and multivariate statistical procedures, such as analysis of variance (ANOVA), factor analysis, cluster analysis, and categorical data analysis. PASW Statistics is particularly well-suited for survey research, though by no means is it limited to just this topic of exploration. This handout (Descriptive Statistics) introduces basic skills necessary to run PASW Statistics. It includes how to create a data file and run descriptive statistics. It is especially tailored to answer three research que
