Circular Histogram Engine for Effortless Statistical Evaluation
Circular Histogram Engine for Effortless Statistical Evaluation (CHEESE) makes circular histogram creation simple. Just enter a list of values, and optionally labels, and CHEESE generates the histogram in realtime.
EdenGraph is a graphing calculator, built for Mac OS X, which is able to plot two-dimensional graphs using standard algebraic or trigonometric functions. Many mathematical packages only allow for static, rendered images of graphs, whereas EdenGraph lets the user dynamically shift, track, or magnify the current graph.
G*Power 3 is a statistical power analysis program. It covers many different statistical tests of the F, t, chi-square, and z test families as well as some exact tests.
(commercial) GraphClick is a graph digitizer software which allows to automatically retrieve the original (x,y)-data from the image of a scanned graph or from a QuickTime movie.
KnotPlot visualize mathematical knots in 3 or 4 dimensions. Knots can be loaded from a database of almost 1000 knots and links or sketched by hand in three dimensions. Also, knots may be constructed via the Conway notation or using a tangle calculator.
Plot is designed for everyday plotting, it is easy to use, it create high quality plots, it allows easy and powerful manipulations and calculations of data and it is free.
QuickTTestX is a programme for calculating means, SDs and SEMs and testing the significance of differences using Student's t-test.
R for Mac OS X
a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories
SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility.
