## mean,

in statistics, a type of averageaverage,
number used to represent or characterize a group of numbers. The most common type of average is the arithmetic mean. See median; mode.
. The arithmetic mean of a group of numbers is found by dividing their sum by the number of members in the group; e.g., the sum of the seven numbers 4, 5, 6, 9, 13, 14, and 19 is 70 so their mean is 70 divided by 7, or 10. Less often used is the geometric mean (for two quantities, the square root of their product; for n quantities, the nth root of their product).

The novel had been mostly forgotten when Randall Jarrell reminded readers of its existence, pointing out in a New York Times article in 1955 that he had been "getting people to read it for ten years, with the most dazzling results." Elizabeth Hardwick, in a New Republic piece of the same year, praised its "truly radical power and authenticity," adding that Stead's "name means nothing to most people...none of [her] work is in print...The dust, grimly, meanly collecting, has fallen upon work of sheer astonishment and success." Randall Jarrell's introduction to the 1965 republication, ten years after his Times mention, again called the novel an overlooked masterpiece of universal appeal.
