Americans encounter basic statistics and charts in everyday life. Many media reports cite studies in health, social, economic, and political trends. Understanding statistical concepts is important to understanding the meaning of these studies and, consequently, to scientific literacy (Crettaz von Roten 2006). One test of these concepts included on the 2008 GSS found that 74% of Americans could read a simple chart correctly and 66% understood the concept of "mean" in statistics. Understanding these two concepts was associated with both formal education and the number of math and science courses taken. Older respondents were less likely than younger adults to respond correctly to these two questions. Men and women were about equally likely to answer these questions correctly (appendix table 7-15).
