Joshfire Framework MicOsiris Statistical Analysis and Data Management Software SpringSource.org | Basic Statistics Descriptive Statistics "True" Mean and Confidence Interval. Probably the most often used descriptive statistic is the mean. The mean is a particularly informative measure of the "central tendency" of the variable if it is reported along with its confidence intervals. Shape of the Distribution, Normality. More precise information can be obtained by performing one of the tests of normality to determine the probability that the sample came from a normally distributed population of observations (e.g., the so-called Kolmogorov-Smirnov test, or the Shapiro-Wilks' W test. The graph allows you to evaluate the normality of the empirical distribution because it also shows the normal curve superimposed over the histogram. Correlations Purpose (What is Correlation?) The most widely-used type of correlation coefficient is Pearson r, also called linear or product- moment correlation. Simple Linear Correlation (Pearson r). How to Interpret the Values of Correlations. Significance of Correlations.
Statistical Services Centre - Training and Consultancy in Statistics We have developed various software resources that we use in our training and consultancy work. The following can be downloaded: Instat, a general statistical computing package SSC-Stat, an "add-in" to strengthen the capabilities of the spreadsheet package Excel Diversity, an Excel "add-in" that provides functions for calculating diversity indices Statistical Games A set of statistical games have also been developed at Reading. These are simulation exercises based on real life problems that have been adapted at Reading for educational purposes. Click here for more details.

PSPP GNU PSPP Screenshots This page demonstrates some of PSPP's capabilities and the various ways it can be used. It's not intended to be a tutorial, or a substitute for the reference manual, but a brief demonstration of what PSPP can do. Note: This page is graphics heavy! Click on any of the images to see large scale versions. Compatibility PSPP is designed as a Free replacement for SPSS. In a few instances, the default behaviour of PSPP differs where the developers believe enhancements are desirable or it makes sense to do so, but this can be overridden by the user if desired. Ways of Using PSPP PSPP can be used in several different modes, depending on the requirements, experience and preference of the user. Terminal Mode One way to use PSPP is from a terminal. Graphic User Interface Users familiar with other software may prefer the graphic user interface, which allows you to define data without needing to become familiar with the PSPP syntax.
