м.б. ranged data sequence |
consider: The median or midpoint is a property value dividing/splitting the row of data arranged/organized in a downward order into two equal parts, the first one containing data valued above the median value and the other one - below the midpoint |

a set of data items/numbers ordered by value/ranked in order/ arranged in either either ascending or descending order (The median is usually calculated for numeric variables, but may also be calculated for other sequenced variables of a categorical nature) 50% of the items/numbers |
My try: The value of an attribute (variable) which divides an ordered set of numerical data into equal parts (halves, subgroups) where 50% of the data set will have an attribute value not exeeding the median, and 50% - not less than (greater or equal to) the median. |
that divides |
Susan, have a look at this. http://www.math.uni-bonn.de/people/ilyad/anglit/AJL.htm#ch3 The best RU>EN tech/sci dictionary ever compiled (as good as Ignatiev Callaham. Every entry has been rechecked and reconciled). |
Median From Wikipedia, the free encyclopedia Jump to: navigation, search This article is about the statistical concept. For other uses, see Median (disambiguation). In probability theory and statistics, a median is described as the number separating the higher half of a sample, a population, or a probability distribution, from the lower half. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one. If there is an even number of observations, the median is not unique, so one often takes the mean of the two middle values. At most half the population have values less than the median and at most half have values greater than the median. If both groups contain less than half the population, then some of the population is exactly equal to the median. For example, if a < b < c, then the median of the list {a, b, c} is b, and if a < b < c < d, then the median of the list {a, b, c, d} is the mean of b and c, i.e. it is (b + c)/2. The median can be used when a distribution is skewed or when end values are not known. A disadvantage is the difficulty of handling it theoretically.[citation |
