| median |
the midpoint in a series of numbers; half the data values are above the median, and half are below. For example, in the odd series 1, 4, 9, 12 and 33, 9 is the median. In the even series 1, 4, 10, 12, 33 and 88, 11 is the median (halfway between 9 and 12). Note, the median is not necessarily the same as the AVERAGE (or mean). For example, the median of 2, 6, 10, 22 and 40 is 10 but the average is 18.

Statistically derived single dose of a chemical that can be expected to cause death in 50% of a given population of organisms under a defined set of experimental conditions. This figure has often been used to classify and compare toxicity among chemicals but its value for this purpose is doubtful. A commonly used classification of this kind is as follows: Category..........................................LD50 Orally to Rat (mg/kg body weight) Very toxic....................................... ...
