We’ve been expanding the free software page, comparing software using standard data files; we will soon be using the same tests on several packages to compare them. In March 2018, we added a forum to get your thoughts and input; and in April 2018, we added a guide to using SPSS, a little guide on Sierra/High Sierra “signing warnings,” and updates to our Jamovi and free software pages. Contact us about sponsoring this site. For a relatively small monthly fee, you can eliminate all other ads from MacStats.org and we will instead carry banners advertising your own business.
We do not get any financial reward from any software maker except via the advertising agencies — and we do not usually know who is advertising with us.
