![]() Here is a partial list of features missing from Excel, but present in Prism: The data within Prism are automatically updated. Edit the data within Excel (or edit other values which contribute to the calculation of the values you pasted) then close the Excel worksheet. Instead, you can double-click on the data block in Prism to return to Excel. In either case, you won't be able to edit those values in Prism (without breaking the link). ![]() ![]() With the Windows version, you can choose to paste a link to the original Excel file, or you can paste an embedded Excel worksheet within Prism. With the Mac version of Prism, simply paste the values into Prism. Many, perhaps most, Prism users also use Excel and copy and paste data into Prism for analysis and graphing. Prism's graphs and layouts can be exported directly to PowerPoint, or as high-resolution Tiff, PDF, or EPS files. Prism also provides tools to automate repeated analyses and graphing. Prism can create many graphs that Excel simply cannot, including scatter graphs, box-and-whiskers plots, and survival curves. Prism also allows users to create and customize presentation-quality graphs, with features such as automatic error-bars, log axes, offset and discontinuous axes, and custom ticks and grid-lines. Prism is designed specifically for research scientists and makes it easy to perform the analyses scientists need, including t-tests, one- and two-way ANOVA, parametric and non-parametric tests, curve fitting, survival analyses and more. Likewise, Excel does not have the flexibility to create the presentation-quality graphs most scientists require. While it is possible to coax Excel to fit curves, it isn't easy and the results are not complete (no standard errors or confidence intervals of the parameters). Excel does not make quality scientific graphs, and can perform only a few statistical analyses. Microsoft Excel is a general business application that is very good at storing and manipulating large amounts of data.
