PSPP. GNU PSPP is a program for statistical analysis of sampled data.
It is a free as in freedom replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package. PSPP is a stable and reliable application.

Free Qualitative Data Analysis Software. SPSS Starter Kit. SPSS Starter Kit This page is intended for people who: These materials have been collected from various places on our website and have been ordered so that you can, in step-by-step fashion, develop the skills needed to conduct common analyses in SPSS.
Although SPSS has a very nice point-and-click interface, we suggest that you learn to use SPSS syntax. Almost all procedures and operations in SPSS can be done either via point-and-click or syntax. While using the point-and-click interface may seem easier at first, you will quickly find that it makes documenting what you are doing very difficult. Getting familiar with SPSS. ViSta: The Visual Statistics System. The F-Ratio: The heart of ANOVA is analyzing the total variability into these two components, the mean square between and mean square within.
Once we have analyzed the total variability into its two basic components we simply compare them. The comparison is made by computing the F-ratio. Introduction to SPSS for data analysis: overview of SPSS. Getting Started with SPSS for Windows. Interactives archive: Physics and Math. Software. Regression Tools - Online Multiple Linear Regression. This page allows you to work out multiple linear regressions, also known as multilinear regressions or multiple linear least squares fittings.
For the relation between several variables, it finds the linear function that properly fits a given set of data points. The result is not necessarily the best possible, but usually it is a very good one and further improvement posibilities are very small. In the case that the number of variables is equal to the number of data points an hyperplane containing all the points results. • Copy & Paste: You can copy and paste data directly from a spreadsheet or a tabulated data file in the box below.
Any character that cannot be part of a number -space, comma, tabulation...- is considered a column separator. . • Insert manually & See details: If you prefer you can insert all the points manually, for which you first have to specify the number of data points.

One-Way ANOVA. Minitab. Atomic Training. Graphpad quickCalcs. The Free Statistics Calculators Website - Home. Free Statistical Software - FreeStatistics.info. WikiCalc Beta Test Home. WikiCalc is currently released in late Beta test.
This means that it is not fully tested, has bugs, but has all of the features that will be in the 1.0 release. It is quite useful in its own right and is able to create, publish, and maintain a wide variety of web pages. For example, this page and many of the ones it links to about wikiCalc were created with the wikiCalc Beta. (The graphical design comes from a CSS file and the side bar is in a simple custom template. Much like a blogging tool, you can automatically wrap the output in static nice-looking stuff if you don't want the default.) The Beta release is available for use on Windows, Mac, Linux/Unix, and other platforms that can run the Perl language.

A directory of software sources for analysing animal abundance. Free Statistical Software. Software. One can argue that there is a tradeoff in statistical software between its "ease of learning" and its "power".
Typically, those packages that are easy to learn are menu-driven and point-and-click driven. Some even have features designed soley for pedagogical purposes. On the other hand, other packages are designed to provide a great number of powerful and fast statistical tools as well as data management capabilities.
Warning: this page is by no means intended to be comprehensive. Merely a reflection of my own experience. High Scorers on the "Ease of Use" scale: Fathom -- this is predominantly a teaching tool, but in recent years has been expanded to included multiple regression and other useful tools. Universität Düsseldorf: G*Power. Statistics With Excel? Excel is available to many people as part of Microsoft Office. People often use Excel as their everyday statistics software because they have already purchased it.

The population mean for a finite population of size N is obtained by adding together the values in the data set and dividing by the population size N. Notation: The standard notation for the sample mean is given by , read as "x-bar".Notation: The standard notation for the population mean is given by the Greek symbol m, read as "mu".Formula: The standard formula that is used to compute the sample mean is.

News. Qualitative Data Analysis Software. Computer Assisted Qualitative Data Analysis Software, CAQDAS--i.e. the application of qualitative data analysis software--has become very common among qualitative researchers nowadays. The Comprehensive R Archive Network. Announcing Statistics with Interactive R Learning Software Environment. Editor's note: This post was written by Nick Carchedi, a Master's degree student in the Department of Biostatistics at Johns Hopkins.
He is working with us to develop software for interactive learning of R and statistics. Inspired by the relative lack of computer-based platforms for learning statistics and the R programming language, we at Johns Hopkins Biostatistics have created a new R package designed to teach both topics simultaneously and interactively. Accordingly, we’ve named the package swirl, which stands for “Statistics with Interactive R Learning”.
