5. There's power in precise terms.
"Roland Fryer pointed to the gap in educational achievement between black and white children, and suggested a solution: Figure out what those charter schools that have closed the gap, or at least narrowed it, are doing right, and then distribute those techniques to the public schools."

This is an example of theory vs. hypothesis. He believes since children in charter schools are getting a better education through the school. However, many other factors effect this "observation." He should take into consideration the home environment, how much there parents are involved in their education( such as helping with homework and studying), and many other possible factors effecting the outcome. His hypothesis to distribute the techniques used in private schools to public schools may sound good in theory, but many other factors may need to be changed in the childs life in order to receive a better education. http://online.wsj.com/article/SB10001424052702303348504575184051900295586.html

6. Correlation is not causation.
"Emily Oster, a young economist, argued that getting people to improve their health behaviors is a hard problem. While diabetes could be significantly reduced if diabetics would just lose weight, she noted, overweight diabetics actually gain weight after they have been diagnosed."

This could possibly be "pointing to a link between two things and jumping to a conclusion that assumes cause." People with diabetes are usually overweight. If so, they could continuously gain weight all the time, even before being diagnosed with diabetes. Just because a patient got diagnosed with diabetes and gained weight at the same time does not mean that they are directly correlated. http://online.wsj.com/article/SB10001424052702303348504575184051900295586.html
