__n__Average, mean, median, norm, par denote something and usually a number, a quantity, or a condition that represents a middle point between extremes. Of these words average, mean, median, and par are also used as adjectives.Average is an arithmetical term applied to a quotient obtained by dividing a total by the number of items entering into this total so that the quotient represents the value each item would have if all were alike; thus, the*average*of 10, 12, 14, 16, 18, 20 is 15 (that is, 90÷15=6). Such averages are computed to give one a fair estimate of a group or a series in which there are inequalities{his

}*average*for his high school course was 82{the daily

}*average*of the apple pickers was 25 bushelsWhen (as in sports) the total represents the number of chances taken or of opportunities offered or provided, the*average*is obtained by dividing the number of successes or successfulperformances by this total. Such an average may be expressed as a percentage or a permillage and gives a fair estimate of a player’s performance and a basis for comparison with others; thus, a baseball first baseman who handles a total of 1114 chances and makes 6 errors has a fielding*average*of .9946 (that is, 1108÷1114); a baseball batter who is credited with 605 appearances at bat and has made 201 hits has a batting*average*of .332 (that is, 201÷605). A similar method is used in estimating probabilities (as the chances of death for a person between given ages and the length of the period between recurrences of an unpredictable phenomenon); thus, the*average*of mortality for persons of a given age is computed from statistics of deaths at that age and of the population group consisting of persons of that age.*Average*also may be applied to a concept of what is the typical or ordinary person or thing of its kind (see also*average*, under MEDIUM){the boy is above the

}*mean*, and lives contentedly between the little and the great—*Cowper*In its mathematical use*mean*is more general than*average*(for which another name is*arithmetical mean*): it covers also the*geometric mean*, that is, the square root of the product of two numbers or quantities (or the*nth*root of the product of__n__quantities); thus, 10 is the*arithmetical mean*or*average*of 4, 16; while 8 is the*geometric mean*of 4, 16.Median refers to a midway point in position; in statistics it names the figure or quantity which represents the point at which there are as many instances below as there are above it; thus, the*average*of a group of 5 workers earning respectively 6, 8, 10, 16, and 20 dollars a day is 12 dollars a day, whereas the*median*for the same group is 10 dollars, because one half of them earn less than 10 dollars a day and one half more.Norm suggests a rule for guidance or a definite pattern to be followed; it also denotes especially in such fields as psychology and sociology, an average, whether mathematically computed or estimated, of performance or achievement of a group, class, or category that can be set up as a standard for or a minimum of accomplishment by a similar larger group, class, or category; thus, a course of study for a particular school grade is based upon a*norm*determined by the performance of children of the age, experience, and background commonly found in that grade{crime is merely a name for the most obvious, extreme, and directly dangerous forms of . . . departure from the
