GraphPad Prism 6.0e Mac OS X

GraphPad Prism was originally designed for experimental biologists in medical schools and drug companies, especially those in pharmacology and physiology. Prism is now used much more broadly by all kinds of biologists, as well as social and physical scientists. More than 200,000 scientists in over 110 countries rely on Prism to analyze, graph and present their scientific data. It is also widely used by undergraduate and graduate students.

What's New in Prism 6
Make the switch to Prism 6
Prism 6 offers more statistical analyses, more kinds of graphs, better learning tools and is more efficient to use. But Prism is still Prism! You can switch to Prism 6 with almost no learning curve, and can try the Prism 6 demo without removing Prism 5. Here are some of the highlights.

New Analyses – ANOVA, multiple comparisons and more
- Two-way ANOVA with repeated measures in both factors.
- Multiplicity adjusted (“exact”) P values for multiple comparison tests.
- New post tests - Fisher’s unprotected Least Significant Difference (LSD) and Holm-Sidak.
- Run a set of t tests (one per row) at once, correcting for multiple comparisons with Bonferroni or by contolling the False Discovery Rate (FDR).
- Follow two-way ANOVA with tests for simple or main effects. Don't worry if you don't know what that means - Prism 6 presents those choices graphically so the meaning is obvious.
- Greenhouse-Geisser correction in repeated measures one-way ANOVA to avoid the need to assume sphericity.
- Grubbs’ outlier detection. Our most popular QuickCalc web calculator is now part of Prism.
- Kolmogorov-Smirnov test to compare two groups (an alternative to the Mann-Whitney test).
- Ratio t test

Improved curve fitting
- Fit to implicit and differential models.
- Write more complex models.
- Quicker interpolations. Prism 6 adds a new analysis that streamlines the process of interpolating values from standard curves.
- Weight your fit by 1/Y^k
- Monte-Carlo simulations without writing scripts.

Pie charts and more
- Prism 6 adds a new kind of data table for parts of whole data. Plot pie charts, donut plots and more.
- Compare the observed distribution of values with theoretically expected values with the chi-squared or binomial test.
- Compute each value as a fraction or percentage of the column total.

Work with larger data sets
- Enter data in up to 256 data set columns.
- Enter up to 256 subcolumns per data set (up from 52 in Prism 5). This lets you compute repeated measures two-way ANOVA with more subjects.

Work more efficiently
- Faster. Faster saving, faster closing, faster nonparametric calculations, faster graphing, faster, crisper screen redraws.
- Format several data sets at once. Want to plot alternating columns as dotted lines? Now you can do it in one step.
- View and edit all of your column titles at once. Great for large files!
- Choose the size, shape and color of your data points right from the data table. You can even select any contiguous block of data and make choices for that specific subset of your data table.
- WAND. If you love MAGIC, you will love the new WAND. While MAGIC reformats graphs, the WAND analyzes and graphs a new data table to match what you have done to another.
- Paste link values from results tables into a data table so everything updates automatically. This also works if you want to link data from one data table to another.

Plays well with others
- Export graphs in more formats.
- Better TIFF compression means smaller files and faster exporting.
- Import more types of graphic files into your Prism layouts.
- Control whether to use periods or commas as a decimal separator from within Prism.
- Choose how to handle excluded values when you export/paste from Prism data tables.

Requirements
