PSPP. PSPP 2.0.0 has been released. 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. A brief list of some of the PSPP's features follows below. Support for over 1 billion cases. PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data. Downloading PSPP There are some additional ways you can download or otherwise obtain PSPP. Documentation Development. One-Way ANOVA Calculator. The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously. To use this calculator, simply enter the values for up to five treatment conditions (or populations) into the text boxes below, either one score per line or as a comma delimited list. Select your significance level, give your data a final check, and then press the "Calculate" button. Note: You'll find a repeated-measures one-factor ANOVA calculator here, if that's what you require.

No calculation has yet been performed. Post Hoc Tukey HSD (beta) The Tukey's HSD (honestly significant difference) procedure facilitates pairwise comparisons within your ANOVA data. The F statistic (above) tells you whether there is an overall difference between your sample means. A couple of things to note. SISA allows you to do statistical analysis directly on the Internet.

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. Please see our seminar on SPSS syntax for some tips on ways to ease yourself into using SPSS syntax. Getting familiar with SPSS Class notes with movies: There is no point in waiting to take an introductory class on how to use SPSS. Getting familiar with the statistical procedures What statistical analysis should I use? Getting familiar with the output Going further. 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. For independent-measures ANOVA the F-ratio has the following structure: or, using the vocabulary of ANOVA, Characteristics of the F-ratio The numerator and denominator of the ratio measure exactly the same variance when the null hypothesis is true.

Thus: when Ho is true, F is about 1.00. F-ratios are always positive, because the F-ratio is a ratio of two variances, and variances are always positive.

There must be between 2 and 10 levels for each of the two factors. Then click on the link below the text entry fields, which will create all the necessary textboxes. Each textbox is preceded by the label "Group a,b", where a and b are the level indices for the first factor and second factor respectively. There will be n_1 \times n_2 boxes, where n_1 is the number of first factor levels and n_2 is the number of second factor levels.

Please click to add all the textboxes Simply click on the link near the top to add text boxes. Select multiple single column CSV files to populate the text boxes by repeatedly pressing the Choose File button - there must be one distinct (and differently named) file for each text box i.e. one file per group. There is a graph at the bottom which will display means for all the groups, once the calculate button is pressed. Results pending... One-Way ANOVA.

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. The Beta release is available for use on Windows, Mac, Linux/Unix, and other platforms that can run the Perl language. The program is written by Dan Bricklin (me) and is available under a GPL 2.0 license.

This version includes a "Demonstration Setup" option to get you up to speed quickly if you just want to see what a browser-based spreadsheet feels like. WikiCalc is currently aimed at users who are comfortable figuring out how best to use a new tool. Online Statistics Calculator, basic math statistics, Tutorial.

Bayesian inference using Gibbs sampling. Other packages: ADE-4. 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. DataDesk -- this probably wins on both the "Ease" and "Power" scales.

DataDesk can also be bundled with ActivStats, in which case it becomes a fairly complete textbook/software package. Tinkerplots -- I'm not sure whether this is easy to use or not. High Scorers on the "Power" scale: Universität Düsseldorf: G*Power. 17 March 2020 - Release 3.1.9.7 Windows Changed the behavior of the “X-Y plot for a range of values” which allowed plotting graphs after changing input parameters in the main window without hitting the “Calculate” button which, however, is required to update the “X-Y plot for a range of values” with the new input parameters from the main dialog. 21 February 2020 - Release 3.1.9.6 Mac and Windows Fixed a bug in z tests: Generic z test: Analysis: Criterion: Compute alpha: The critical z was calculated incorrectly.

Fixed a bug in t tests: Linear bivariate regression: One group, size of slope: |sy/sx| was sometimes calculated inccorrecty. 14 January 2020 - Release 3.1.9.5 Mac Fixed a bug that caused the “Options” button (which is available for some tests in the main window) to disappear when “Hide distributions & control” was selected. 6 February 2019 - Release 3.1.9.4 Fixed a bug in t tests: Linear bivariate regression: One group, size of slope. 7 July 2017 - Release 3.1.9.3 Mac and Windows:

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. Excel’s limitations, and its errors, make this a very questionable practice for scientific applications. For business applications where questions might be simpler and precision not as necessary, Excel may be just fine.

Below are some of the concerns with using Excel for statistics that are recorded in journals, on the web, and from personal experience. References for more detail are listed at the bottom of this page. Some advice from others:“Meanwhile, researchers should continue to avoid using the statistical functions in Excel 2007 for any scientific purpose.” - Yalta (2008), ref 1 below “... it is not safe to assume that Microsoft Excel’s statistical procedures give the correct answer.
