For a relatively lightweight app (0.8 MB) SciStatCalc v 1.3 now has numerous tests, that will come in handy for hypothesis testing and data analysis.
The tests include: Mann-Whitney U-test, Unpaired Student's t-test, Wilcoxon Signed Rank test, Paired Student's t-test, Linear regression, Spearman's Rank Correlation test, Pearson Correlation test, Shapiro-Wilk test, chi-squared test, Bartlett's test, Kruskal-Wallis test, One-way ANOVA test and Two-factor ANOVA.
Using these tests is easy - simply enter data into the appropriate text boxes. Switching between these tests is even easier - all you need is to swipe left or right.
