Recently, Greg Laughlin, the founder of a new statistical software called Statwing, let me try his product for free. I happen to like free things very much (the college student is strong within me) so I gave it a try.

I mostly like how easy it is to use: For instance, to relate two attributes like Age and Income, you click Age, click Income, and click Relate.

So what can Statwing do?

Summarize an attribute (like “age”): totals, averages, standard deviation, confidence intervals, percentiles, visual graphs like the one below

Relate two columns together (“Openness” vs “Extraversion”)

Plots the two attributes against eachother to see how they relate. It will include the formula of the regression line and the R-squared value.

Sometimes a chi-square-style table is more appropriate. The software determines how best to represent the data.

Tests the null hypothesis that the attributes are independent, by a T-test, F-test (ANOVA) or chi-square test. Statwing determines which one is appropriate.

Repeat the above for a ranked correlation.

For now, you can’t forecast a time series or represent data on maps. But Greg told me that the team is adding new features as I type this.

If you’d like to try the software yourself, click here. They’ve got three sample datasets to play with:
