General description

Unlike all-inclusive programs designed for statisticians, InStat provides statistical routines for scientists, even those with limited knowledge of statistics. Little statistical jargon is used, and extensive help screens are available, eliminating the need for a manual. Data can be entered directly into the built-in spreadsheet or imported from ASCII files. Statistical tests include:
•  Single sample, unpaired, and paired t tests
•  P values and 95% confidence limits
•  Nonparametric analysis (Mann-Whitney, Wilcoxan)
•  Contingency tables: chi-square, Fisher′s exact, confidence limits for the difference between proportions
•  ANOVA, ordinary, or repeated measures of variance
•  F and p values
•  Bonferroni t tests between specified groups
•  Linear regression: slope, intercept, correlation coefficient, standard errors
•  Sample size, requirements for t test and chi-square.
