An article on Oct. 6 about the status of women in the fields of science and mathematics misstated a statistic regarding girls who are taking high-school physics. It was the percentage ofgirls among all high-school physics students of both sexes that rose to 47 percent in 1997 from 39 percent in 1987 — not the percentage of girls taking high-school physics among all high-school girls. The article also misstated the status of a woman hired by the mathematics department at Yale University for a tenure-track position in 2010. She is yet to come up for tenure. She was not denied it.
