## Prism 8 Analyze, graph and present your scientific work.

The preferred analysis and graphing solution purpose-built for scientific research. Join the world’s leading scientists and discover how you can use Prism to save time, make more appropriate analysis choices, and elegantly graph and present your scientific research.

## Comprehensive Analysis and Powerful Statistics, Simplified

### Organize Your Data Effectively

Unlike spreadsheets or other scientific graphing programs, Prism has eight different types of data tables specifically formatted for the analyses you want to run. This makes it easier to enter data correctly, choose suitable analyses, and create stunning graphs.

### Perform The Right Analysis

Avoid statistical jargon. In clear language, Prism presents an extensive library of analyses from common to highly specific—nonlinear regression, t tests, nonparametric comparisons, one-, two- and three-way ANOVA, analysis of contingency tables, survival analysis, and much more. Each analysis has a checklist to help you understand the required statistical assumptions and confirm you have selected an appropriate test.

### Get Actionable Help As You Go

Reduce the complexity of statistics. Prism’s online help goes beyond your expectations. At almost every step, access thousands of pages from the online Prism Guides. Browse the Graph Portfolio and learn how to make a wide range of graph types. Tutorial data sets also help you understand why you should perform certain analyses and how to interpret your results.

## Work Smarter, Not Harder

### One-Click Regression Analysis

No other program simplifies curve fitting like Prism. Select an equation and Prism does the rest—fits the curve, displays a table of results and function parameters, draws the curve on the graph, and interpolates unknown values.

### Focus on Your Research, Not Your Software

No coding required. Graphs and results are automatically updated in real time. Any changes to the data and analyses—adding missed data, omitting erroneous data, correcting typos, or changing analysis choices—are reflected in results, graphs, and layouts instantaneously.

### Automate Your Work Without Programming

Reduce tedious steps to analyze and graph a set of experiments. It is easy to replicate your work by creating a template, duplicating a family, or cloning a graph—saving you hours of set up time. Apply a consistent look to a set of graphs with one click using Prism Magic.

## The Fastest Way to Elegantly Graph and Share Your Work

### Countless Ways to Customize Your Graphs

Focus on the story in your data, not manipulating your software. Prism makes it easy to create the graphs you want. Choose the type of graph, and customize any part—how the data is arranged, the style of your data points, labels, fonts, colors, and much more. The customization options are endless.

### Export Publication-Quality Graphs With One Click

Reduce time to publish. Prism allows you to customize your exports (file type, resolution, transparency, dimensions, color space RGB/CMYK) to meet the requirements of journals. Set your defaults to save time.

### Enhance Collaboration

Share more than your graphs. Prism’s comprehensive record of your data enables effective collaboration with other scientists. All parts of your Prism project (raw data, analyses, results, graphs, and layouts) are contained in a single file that you can share with one click. Now others can easily follow your work at every step, enhancing the clarity of your findings and streamlining your collaborative efforts.

## Discover What’s New in Prism 8!

Introducing an even more powerful Prism featuring enhanced data visualization and graph customization, more intuitive navigation, and more sophisticated statistical analyses.

### Enhanced Data Visualization

### Violin plots

Visualize distributions of large data sets more clearly than with box-whisker or simple bar graphs

### Subcolumn graphs

Organize related subsets of nested data in a single graph

### Smoothing spline

Major improvements in showing general data trends through Akima splines and smoothing splines with improved control over the number of knots, or inflection points

### No more smiles

More intelligent adjustments of data point positions in scatter plots for better looking graphs

### Improved Graphing and Customization Options

### Draw lines and brackets with centered text

Easily annotate your data with asterisks or custom labels

### Automatically label bar graphs

Annotate your bar graphs with values for the means, medians, or sample sizes to emphasize what’s important in your work

### Improved grouped graphs

Easily create graphs that show both individual points (scatter) along with bars for mean (or median) and error bars

### More Intuitive Navigation

### Find related sheets easily

New family panel shows the family of sheets related to the current sheet, and chains of analyses are automatically indented

### Easily navigate between multiple results tables

Analyses with multiple results tables now grouped into a single sheet with tabs for each result table; choose which tabs to show or hide

### Improved Search

Search by sheets with highlights or notes of specified color

### Now Featuring Eight Kinds of Data Tables

### New: Multiple variables data table

Each row represents a different subject and each column is a different variable, allowing you to perform Multiple linear regression (including Poisson regression), extract subsets of data into other table types, or select and transform subsets of the data

### New: Nested data table

Analyze and visualize data that contains subsets within related groups; Perform nested t tests and nested one-way ANOVA using data within these tables

### More Sophisticated Statistical Analyses

### Perform repeated measures ANOVA – even with missing data

Now Prism will automatically fit a mixed effects model to complete this analysis

### Powerful Improvements in regular ANOVA

View cell, row, column, and grand means (or least square means when data is missing); test for homogeneity of variance. For one-way ANOVA, choose a test that does not assume homogeneous variances.

### Nested t test and nested one-way ANOVA

Utilize new types of data tables to perform nested t-tests and nested ANOVA as well as multiple linear regression (including Poisson regression)

### Graph residuals from multiple types of analyses

Test residuals for normality in four different ways, and choose from four different ways to display these residuals

## Discover the Breadth of Statistical Features Available in Prism 8

### Statistical Comparisons

- Paired or unpaired t tests. Reports P values and confidence intervals.
- Automatically generate volcano plot (difference vs. P value) from multiple t test analysis.
- Nonparametric Mann-Whitney test, including confidence interval of difference of medians.
- Kolmogorov-Smirnov test to compare two groups.
- Wilcoxon test with confidence interval of median.

- One-way ANOVA without assuming populations with equal standard deviations using Brown-Forsythe and Welch ANOVA, followed by appropriate comparisons tests (Games-Howell, Tamhane T2, Dunnett T3)
- Many multiple comparisons test are accompanied by confidence intervals and multiplicity adjusted P values.
- Greenhouse-Geisser correction so repeated measures one-, two-, and three-way ANOVA do not have to assume sphericity. When this is chosen, multiple comparison tests also do not assume sphericity.
- Kruskal-Wallis or Friedman nonparametric one-way ANOVA with Dunn’s post test.
- Fisher’s exact test or the chi-square test. Calculate the relative risk and odds ratio with confidence intervals.
- Two-way ANOVA, even with missing values with some post tests.
- Two-way ANOVA, with repeated measures in one or both factors. Tukey, Newman-Keuls, Dunnett, Bonferroni, Holm-Sidak, or Fisher’s LSD multiple comparisons testing main and simple effects.
- Three-way ANOVA (limited to two levels in two of the factors, and any number of levels in the third).
- Analysis of repeated measures data (one-, two-, and three-way) using a mixed effects model (similar to repeated measures ANOVA, but capable of handling missing data).
- Kaplan-Meier survival analysis. Compare curves with the log-rank test (including test for trend).
