(Phys.org)—For many Americans, the single biggest problem facing the country is the growing wealth inequality. Based on income tax data, wealth inequality in the US has steadily increased since the mid-1980s, with the top 10% of the population currently owning about 73% of the country's wealth. In a new paper published in PLOS ONE, researchers have quantitatively analyzed several of the major factors that affect wealth inequality dynamics, and found that the most crucial factor associated with the recent surge in wealth inequality since the '80s has been the dramatic decrease in personal savings, followed closely by a large increase in the dominance of capital income over labor income.

If you ever read public health research, you've probably encountered the term "Student's t-test," or just "t-test." The experimenters will do this magical test, and suddenly conclude that everything is awesome. But even when you're familiar with the t-test and what it does, very little thought goes into where this came from, or who came up with it. Well, today I'm going to tell you the origins of this staple of public health research.
