statistical analysis and inference software for windows covering everything from average, mode and variance through to hypothesis analysis, time series and linear regression. includes online help, tutorials, graphs, summaries, import/export, customisable interface, calculator, live spell check, install/uninstall and much more. - single, dual (paired and unpaired) and multiple data analysis (multivariate analysis not in lite version). - data can be either for sample or population. - data can be time based for time series analysis. - data can be entered as raw data, grouped data, or as summary data. - raw data can be converted into grouped data. - raw data can have in-built transformations applied to them. - raw data can have random values meeting user defined criteria. - data can be fully documented and stored in datalists. - standardisation of data around given mean/standard deviation. - datalists are grouped together in workbooks - one workbook is opened at a time and can contain many datalists. - sample size calculations. - random value lists for sampling. - statistical summary including: mean, median, mode, variance, standard deviation, kurtosis, skew, etc. - comparison of statistics for raw and grouped of the same data. - graphs and charts including: histograms, line graphs, pie graphs, ogives, scatter diagrams, rootograms, bar charts and more. - inference and hypothesis analysis of a single population - including the mean, the variance and proportions. - inference and hypothesis analysis of two populations - including difference of the mean, ratio of the variance, difference of proportions. - analysis of variance (anova) (not in lite version). - linear regression with transformations of the dependent variable. - multiple regression with transformations of the dependent variables (not in lite version). - moving averages. - trend analysis of time series data. plus more.
