Statwing is described in its crunchbase profile as “Web-based statistical analysis software that speaks in plain english instead of arcane stats jargon.” (Crunchbase, for those who don’t know, is a directory of technology companies.) The founders are a pair out of Stanford, Greg Laughlin (whose background is in the social sciences) and John Le (whose background is in CS), which seems like a good pair for something like this.
They’re not live yet, but if you sign up at their website they’ll let you know when Statwing is ready.
(Disclaimer: I don’t know these people, and I haven’t seen the product, but this seems like a niche that could use filling.)
