The median salary is not as likely than the mean salary to be skewed by outliers, for example, an extremely high salary or an extremely low salary that only a few people may earn. For example, when you put the earthworm farmers' salaries in numerical order, you discover that the median is $19,000.
Most spawning activity occurs at water temperatures around 10 C (50 F). Spawning can take place in streams or along shorelines. Rainbow smelt are found in streams and rivers only during their spawning migration. Females sized 185 to 224 mm (7.3 8.8 in) in length can release from 21,000 41,000 eggs each (Becker 1983).
To create the high heat needed to smelt iron, smiths pumped air from a bellows through the tuyere (nozzle). The furnace was filled with charcoal and iron ore and the charcoal was then set afire. When the temperature rises above 2,800 deg.F, the iron flows from the ore and forms blooms. Using large tongs, the blooms of iron were pulled from the oven and placed on an anvil. A striker would then hammer the lumpy piece of raw iron into a flat, rectangular bar.
