WINKS is the Windows version of KwikStat, a statistical analysis package with popular data analysis and graphing procedures for business and scientific research.
WINKS helps you decide on the appropriate analysis to use, reads data from the keyboard or files, performs the analysis, and offers interpretation of results. Data analysis includes descriptive statistics, T-tests and Analysis of Variance, Non-parametric analyses, frequency and crosstabulation, regression and correlation, survival analysis, and graphs.
Descriptive statistics include mean, standard deviation, variance, median, minimum, maximum, standard error of the mean, percentiles, Tukey 5 number summary, confidence intervals, and more. Descriptive graphics include a histogram with a normal curve fit, a box-and whiskers plot, cumulative normal and cumulative distribution graph.
T-tests and Analysis of Variance (ANOVA) features include independent group t-tests and analysis of variance (up to 20 groups), paired t-tests and repeated measures analysis of variance, single sample analysis of variance and Dunnett's test. You can perform most of these analyses from raw data or from summary information.
Non-parametric analyses include Mann-Whitney, and Kruskal-Wallis analyses for independent groups. Friedman's test is provided for paired or repeated measures analysis. Cochran's Q test is provided for dichotomous data analysis.
Frequency and Crosstabulation includes Goodness of Fit test, frequency distribution, McNemar's test, Chi-square, Fisher exact test (one and two-tailed), Yate's Chi-square, Phi and Cramer's V, Relative Risk, and Odds Ratio.
Regression and Correlation features include simple linear and multiple regression, correlation matrix, R-square and Adjusted R-square, Pearson's and Spearman's coefficient tests for significance, data plots and residual plots, Point biserial correlation.
Survival Analysis includes actuarial and Kaplan-Meier life tables and comparison of survival curves.
Graphs include histogram with bell curve fit, comparison charts including box-and-whiskers plot, mean chart, median chart, and standard error chart. Also available are a multiple group (XY) scatterplot, multiple correlation scatterplot, survival analysis plot, and more. First Impression charts give you a wide range of graph display options including 3D, tape, area, pie and more.
WINKS lets you print the results or capture text and graphic output to include in reports or other word processed documents. The program reads and writes dBase and ASCII files, importing data from any other program. |
