  2. Include variable labels and category labels (formats) - optional
  3. Supports missing values
  4. WINKS allows you to use raw or summary data on many analyses.

Analyze your data & get professional and understandable results
  1. WINKS provides many statistical procedures to choose from (see below, and also see Professional Edition)
  2. The optional WINKS "show hypothesis and write-up" option explains the hypothesis tested and walks you through the decision-making process to help you understand the results
  3. WINKS 7 provides enhanced graphs for most analyses
  4. A WINKS diagram in the manual helps you select the correct procedures to analyze your data

 Report results -- we'll help you with your write-up
  1. WINKS provides sample write-ups using APA format to help you describe your results
  2. Most analyses include a graph that explains your conclusions

 Overall - WINKS can help you get the enswers you need
  1. We sat down with students and researchers to design WINKS to fit your needs.
  2. As a result, WINKS provides you with more hand-holding help than any other statistical package -- from data entry to interpretation of results.
  3. A number of on-line tutorials are available to help you analyze your data.
  4. We provide you with a quick start-up tutorial that will get you up and running within 30 minutes.
  5. Satisfaction guaranteed -- 30 day money back if WINKS is not what you need.

WINKS SDA BASIC performs standard statistical calculations such as:
  • Descriptive statistics (means, standard deviations, median, coefficient of variation, skewness, kurtosis, extremes - highest and lowest values, etc.) plus graphs that include a Histogram, Cumulative Distribution, Cumulative Normal, and Normal Probability Plot
  • Tests for normality (Lilliefors/Kolmogorov-Smirnov, Anderson Darling)
  • Confidence intervals, percentiles, Tukey 5-number summary
  • Cp and Cpk analysis (for Quality Control processes)
  • Descriptive statistics by group (up to 2 factors)
  • Descriptive statistics from counts
  • Custom (user selected) percentile calculations
  • Calculate permutations and combinations, Counting outcomes, adding and multiplying probabilities
  • Calculate common transformations with a few clicks, including
    • z-score
    • square root
    • natural log
    • log base 10
    • add/subtract a constant
    • raise to a power
    • difference between 2 dates (month, year, week, etc)
    • Box-Cox transformation
    • difference a time series
    • lag
    • autoregressive transform
    • autocorrelations
    • partial autocorrelations
  • Calculate p-values for Normal, t, Chi-Square and F statistics
  • Write calculation steps that can be replayed (Kwikstat code file)
  • Calculate indicator variables from categories
  • Graph features: Histograms (single or by group), bar charts, stacked bar charts, pie charts, line charts, time series plots, stem and leaf, scatterplot, fitted regression line, matrix of scatterplots,  etc.
  • Create Excel charts directly from WINKS
  • Pie and Bar charts from keyboard data
  • t-tests -- single sample, independent group and paired t-test
  • t-test from summary data
  • One-Way Analysis of variance with multiple comparisons (Newman-Keuls, Scheffe, Tukey) from raw or summarized data and Simultaneous confidence limits on differences for multiple comparisons
  • Repeated Measures ANOVA with post hoc multiple comparisons
  • Dunnett's test (from raw or summarized data)
  • Frequency tables
  • Goodness of fit analysis
  • Crosstabulation (rxc) Chi-Square analysis -- with multiple comparisons of proportions for 2xc and rx2 tables
  • Fisher's Exact test
  • Correlation (Pearson and Spearman)
  • Comparison of proportions
  • Point biserial correlation
  • Simple linear regression with optional prediction
  • Multiple linear regression with optional prediction
  • Mann-Whitney nonparametric test for two independent group comparison
  • Kruskal-Wallis nonparametric test for three or more independent group comparison, with post hoc nonparametric multiple comparisons (Dunn's Test)
  • Wilcoxon signed rank test and the Sign test for paired group comparison
  • Friedman's test for repeated measures with post hoc nonparametric multiple comparisons
  • Cochran's Q test for comparison of dichotomous data
  • McNemar's test for paired dichotomous data
  • Survival analysis & Life Tables (Actuarial and Kaplan Meier -- comparison by group using Mantel-Haenszel for post hoc comparison of groups)
  • Simulations -- Central limit theorem, confidence intervals, coin flip, and "Monty-Hall" 3 door probability simulation
  • Report generator produces a data custom report

WINKS SDA works on Windows 7, 8, 10 (as well most other Windows verison.) Designed for researchers who need to get statistical answers quickly. Plenty of examples are available to get you started. Hundreds of hours of working with consultants and researchers went in to creating the interface as well as creating understandable examples and program output.Sample Output and Graphs:
