Features: BioStat is biology and medicine oriented statistical software. BioStat 2009 has a robust suite of statistics tools. It also contains graphical analysis methods that are easily accessed. The user interface is easy to use. Even complete beginners can get productive very quickly. Though it is a powerful biology and medicine oriented professional statistical analysis tool, the interface is so simple that even people who have no knowledge of statistics are capable of processing data. Intellectual resources can be better utilized in analyzing data. No need to check and double check if the data was processed correctly. Major groups of analysis that can be done include basic statistics, ANOVA (both MANOVA and GLM ANOVA), non parametric statistics, regression analysis, time series analysis and survival analysis. Basic statistics group includes determining descriptive statistics, normality tests, T test Pagurova criterion and G criterion, Fisher F test, correlation coefficients and covariation, cross tabulation and frequency table analysis etc. Nonparametric statistics group include 2x2 Tables Analysis (Chi-square, Yates Chi-square, Exact Fisher Test, etc.), rank correlations (Kendall Tau, Spearman R, Gamma, etc.), comparing independent samples (Mann-Whitney U Test, Kolmogorov-Smirnov test, Wald-Wolfowitz Runs Test, Rosenbaum Criterion;Kruskal-Wallis ANOVA, median test), comparing dependent samples (Wilcoxon Matched Pairs Test, Sign Test, Friedman ANOVA, Kendall`s Coeff. of Concordance) and Cochran Q Test. Regression analysis tools available are multivariate linear regression, logistic regression, stepwise regression, polynomial regression and Cox proportional-hazards regression. time series tool include Cox regression and probit-analysis (LD50, LD50 SE, cumulation coefficient, LD100 calculation) etc. All these are supported by spreadsheet processor with multi-sheet workbooks, formulae and cell classes, CLE2 support and spell checking. Powerful charts process included can process a wide range of charts.

Overall: This is an excellent program for statistical analysis.
