From Robota Softwarehouse:
With more than 300 statistical routines in your iPad, smallStats is just for you! On the lab bench, in the field, during conferences, and in education, the simple calculations immediately at hand. From ANOVA to Kruskal-Wallis, from circular statistics to k-means clustering and Bayes, just ok for a first quick test.smallStats includes free examples from the biomedical and social sciences. A free iBook 'the smallStats companion' is available in the iBook store, describing the routines and their use.Much attention has been paid to data entry (what is statistics without data !) and the possibility to email the results and the data to (your) email-address. More than 175 routines in your iPad!Results are collected in a separate window for easy transfer outside of the program and outside of the iPad. Plots can be saved in you photo album and so easily transferred to iTunes, iPhoto or any other program, or pasted in an iPad-text with the text editor of your choice.Most routines have an example button (can be hidden), to test the routine, compare the results with textbook solutions and as an aid in learning.Customer review: "Brilliant! This is an incredibly easy to use and powerful app. I've tried many statistics programs from the app store and this is by far the best and most versatile... this app is designed better by far."Parametric:generalother averagesskewness-kurtosisstand.errorsserial independencetest for normalitydifference between meanspaired comparisonsequality of variancescorrelation or regressiondistancescorrelation matrixanovasheffe quickTukey testmultiple regressionploynomial regressionNon Parametric:sign testKruskal - WallisMann - Whitney UContingency tablesJonckheere-TerpstraKolmogorov -SmirnovMcNemar Change testKendall correlation coef.Distributional symmetryCochran QRuns testFisher exactBrown-Forsythe LeveneStatistical TablesNormalFStudent's tChi-squareKruskall-WallisSpearman rhoMann - Whitney UKolmogorov-SmirnofTukey-qBinomial coefficientFisher ZEcostatMark-recaptureQuadrat Size / CountsSequential samplingSimilarityDiversityNiche overlapCircularSpatial distributionMantel associationElementary DNA sequence analysis miscelaneousGoodness of fitresampling (bootstrap, jacknife)BayesKaplan MeierK-Means clusteringsimple Kalman filterrandom number generatoruniformbinomialGaussiangeometricPoissonexponentialhelp with countsheatmapAnd more such as various plots (regression, co-plot, etc.).
