Situated in the middle; lying in a plane dividing a bilateral animal into right and left halves; -- said of unpaired organs and parts; as, median coverts.

median rainfall is calculated by ranking totals from highest to lowest. The middle figure is the median. Annual rainfall averages and medians are usually close. Monthly averages may be well above the median in arid regions where the average is distorted by rare, but torrential, rainfall events. (cf. average).

A measure of central tendency. The exact midpoint of a distribution of data that is ordered from highest to the lowest value.

The middle value when all values are ordered. When there is an even number of values, it is the mean of the two middle values.

The middle observation in a set of data such that half of the observations are larger and half smaller than it.

"Middle value" of a list. The smallest number such that at least half the numbers in the list are no greater than it. If the list has an odd number of entries, the median is the middle entry in the list after sorting the list into increasing order. If the list has an even number of entries, the median is equal to the sum of the two middle (after sorting) numbers divided by two. The median can be estimated from a histogram by finding the smallest number such that the area under the histogram to the left of that number is 50%.

The middle reading, or 50th percentile, of all readings taken. For example, of the readings 10, 13, 9, 16 and 13 {re-ordering these to read 9, 10, 13, 13 and 16}, the median is 13. The mean (or average), is the sum of all values divided by the total number of readings (which in this case equals 12.2).

The middle number of a data set when the measurements are arranged in ascending (or descending) order.

the middle number (if there is an odd number of scores or numbers) or the average of the two middle numbers (if there is an even number of scores or numbers) in a set of data arranged in rank order

The middle number in a sequence of numbers. Also referred to as "midpoint".

is the value of the midpoint variable when the data are arranged in ascending or descending order.

of the plane dividing an animal into right and left halves.

The middle point in a set of ranked scores. It is the value that has the same number of scores above it and below it in the distribution.

The central number in a list; with equal numbers of larger and smaller items.

The central estimate in a dose estimate range. Half the possible doses are above the median; half are below it. A person's actual dose is more likely to be near the median than near the low or the high end of the dose estimate range.

The median for the month is the value of an element which exceeds half the occurrences for that element for that month over the period on record. That is, there is a 50% probability of the element being below the median value. If the values for a month are ranked or arranged in increasing order of magnitude and there are an odd number of values, then the median is the middle value. If the number of observations is even, then the median is calculated by taking the mean of the two middle values. With many meteorological quantities the mean and median values are close and the use of either values is acceptable. Although this may often be the case with annual rainfall, for shorter periods the mean can differ significantly from the median, as the mean can be influenced by an extremely heavy or light value, while the median is not. Hence the median is usually taken as giving a better description of the characteristics of rainfall.

middle value of a set of numbers arranged in order of magnitude.

In statistics the median is the point where half the items in a series are on one side and half on the other side. For example, a series of numbers might be 1, 3, 5, 7, 11. Five is at the median point. Median is not the same as average.

The middle value in a sample sorted into ascending order. If the sample contains an even number of values, the median is defined as the mean of the middle two.

Score dividing the distribution such that 50% of the scores fall above that point and 50% fall below; the 50th percentile

The “middle” number in a group of data. Unlike an average, the median is not sensitive to very high or low results. It is best used for obtaining conservative estimates about a group of data. e.g. for the group of data 1,2,3,4,5, the median is 3 and the average is 3, however, for the group of data 1,2,3,4,50 the median is still 3 but the average is now 12.

The number from a series such that exactly half the numbers are less than it and half greater.... more on: Median

The exact middle; the point which divides a set of values (numbers, scores, amounts) so that exactly half the values are higher than the point and exactly half are lower.

The middle number in a data set when the data are put in order.

This is the central number in a list of items. For example, 2, 4, 7, 8, and 9 have a median of 7.

The middle value of the population characteristic. Half the population has a value above the median and half has a value below. The median is different from the mean in that the median is not influenced much by extremes in the sample. An estimate of the mean square feet per building would be affected by the inclusion of some very large buildings and would not express square footage for a “typical” building. In contrast, the median square feet would not be so affected. For example, “Median Age of the Building” is the middle age of all CBECS buildings; “Median Hours per Week” is the middle number of operating hours of all CBECS buildings; “Median Square Feet per Building” is the middle size (in square feet) of all CBECS buildings; and “Median Square Feet per Worker” is the middle amount of the floorspace per worker of all CBECS buildings.

A measure of central tendency, the median is the middle term in a group that is ranked in order from lowest to highest. The median is less affected by extremely high or low terms in the group, unlike the "average" or "mean" (another measure of central tendency).

A median (also called the second quartile, Q2) is a midpoint of the data: that is, a point at or below which lies at least half the data and at or above which lies at least half the data.

The score of the 'middle' student in a tariff table. Half the students in a tariff table will score at least this, the other half will score no more than this.

the median of a set of numbers is defined to be the middle value when the numbers are arranged in order of magnitude.

Another form of averaging data, the median value is the middle value of a set of data when the data is aranged in terms of magnitude.(e.g. 1234567 - Four would be the median.)

The score corresponding to the point having 50% of the observations below it when observations are arranged in numerical order.

the middle-ranking member of a set of numbers: "Of the numbers 2, 3, 5, 9 and 17, the median is 5 even though the mean is over 7."

if you rank the observations according to size, the median is the observation that divides the list into equal halves.

value dividing a series into two equal parts: those of greater and those of lesser value

The middle value in a group of ranked values that has an equal number of values both above and below it. It indicates the centerline of a distribution, while the mean, or average, can be skewed by a single high or low value.

The middle value of a set of numbers, when they are sorted in ascending order. If you line five people in a row, the middle person in the middle has the median height. A median is usually a very similar number to an average, but is less misleading when a few extreme values distort the average. Take the numbers 2, 3, 5, 5, and 20. There are 5 numbers, and the total is 35, so the average is 7 - but only one of the 5 numbers is above 7. The median is 5, and is less distorted by the presence of the top figure of 19.

The middle value of a series of values. Of the series 1, 2, 3, 4, 10 the median is 3, the average is 4. The median is used because it is less influenced by extreme values than the average

One of several statistics that describe the central tendency in a group. Other measures of central tendency include the mean and the mode. The median is the middle value of all measures in a group. Generally, the number of people in the group with values above the median will equal the number with values below the median. To achieve this, the median might need to be a fictitious value. The median number of legs in a group made up equally of hens and cows is three.

The middle value in a set of a data.

the middle value in a data set; that is, just as many values are greater than the median and less than the median value

The median of a set of data is one way of finding the 'middle' of the data. To findthe median, put all the data in a list in order of size, and pick the piece of datawhich is half way through the list. If there is an even number of values, the medianis half way between the middle pair of values.

The median is that value of the variable which divides the total frequency into two halves.

The middle reading in a series.

See measure of central tendency.

The value of the middle observation. Place the data in order of the size of the observations (rank it). The median is the value of the observation that is halfway along. The median is a type of average but isn't usually what people mean by 'average'.

The median is a measure of central tendency on a scale indicating where a population is centered. The median of the population is the point on the scale that divides the population in half. Half of the population will have values that are equal to or larger than the median, and half will have values that are smaller than the median.

The middle quantity or item in a series arranged according to magnitude.

a measure of central tendency, which appears in the middle of an ordered sequence of values. eg. the median wage is the point at which half made more and half made less. If you place the series in ascending or descending order, the median is the number that divides the series into two parts each containing the same number of data. When there is an even number of data, determine the two central values and take the arithmetic mean.

the middle value (or the average of the middle two values) in a set of data arranged in ascending order

The value in a distribution such that half of the values for scores are larger and half smaller than that value. EX: If 100 scores are available and arranged in numerical order, score number 49 may be 510 and score number 50 may be 514. The median would be 512 â€“ half way between number 49 and number 50, e.g., half the scores are higher and half lower than 512. The median is the 50 th percentile score. [See also mean, mode, percentile

(noun) The middlemost element of a set of numbers, chosen so that most nearly 1/2 of the members of the set are greater/lesser than it. Example: For sets containing an odd number of elements, such as the five member set {2,5,3,4,6} the median is found by ordering the set elements {2,3,4,5,6} and selecting the element in the middle, in this case 4. For sets containing an even number of elements, such as the six member set {2,5,3,4,6,7} the median is found by ordering the set elements {2,3,4,5,6,7}, summing the two middlemost elements, in this case 4+5=9, and dividing this sum by 2, thus the median of the set is 9/2=4.5. See also mean.

The median is an example of a descriptive statistic. It is the value that divides a set of numbers exactly in half when they are placed in order from lowest to highest. In other words, half of the values occur before the median and half of the values occur after the median. The median is often expressed as Md. or Mdn.

The Median is the 'middle value' in your list or series of numbers. When the totals of the list are odd, the median is the middle entry in the list after sorting the list into increasing order. When the totals of the list are even, the median is equal to the sum of the two middle (after sorting the list into increasing order) numbers divided by two.

The score below which 50 percent of the cases in a score distribution fall. If the distribution of scores is distorted by the presence of a few aberrant cases of little importance, the median may be a better summary description of the group than the mean. If the distribution is symmetric, the median and mean will be almost identical. The median is also by definition the 50th percentile.

The measure of central location which divides a set of data into two equal parts.

pertaining to the middle.

The median, a measure of central tendency, is the value of the middle item when the data are arranged from lowest to highest. Since New York State has an even number of counties (62), the median is computed by averaging the two middle observations, point 31 and 32. If New York City Counties' data are not available, the median is the middle observation, point 29 of the range. While the median is not sensitive to outliers and guarantees that 50 percent of the values fall on either side of the value, it may not be representative of all county percents or rates.

The number that falls in the middle between the highest number and the lowest number in a series of numbers. The median is different than an average, which considers all the numbers in the calculation. With an average, high numbers in a set or very low numbers in the set skew the resulting number and distort the picture of what the indicator is supposed to express.

The value of the middle item in an ordered set of data. Fifty percent of observations lie above and fifty percent below the median.

the number in the middle of a set of data arranged in order from least to greatest. For example, 7 is the median of {2,4,7,8,9}. If there are an even number of elements in the set, the median is the mean of the two middle numbers.

The median is the middle value of a series of values when listed in size order. If the number of items is even the median is taken to be halfway between the middle pair of values. So taking the four friends from the 'Mean' example above, their median age is halfway between 69 and 74 - ie 71.5.

Found by arranging numbers from highest to lowest and then taking the middle one. See also average, mean and mode.

The median is a measure of central tendency and is the value for which one-half (50%) of the observations (when ranked) will lie above that value and one-half will lie below that value.

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.

The median is the value above and below which one-half of the observations fall.

the midpoint value obtained by ranking all values from highest to lowest and choosing the value in the middle. The median divides a population into two equal halves.

The middle value of a set of values when they are ordered by rank

the middle number in a set of ordered data (The median of {1,1,1,2,4,6,6} is 2 since 2 is the middle number when all of the numbers are placed in order. If there are an even number of numbers, the median is the mean of the two middle numbers.)

middle number in a set of numerical data when when it is arranged in (either ascending or descending) order; for data sets with an even number of data values then the middle value is a hypothetical value which lies halfway between the two middle values

The middle value in a range of responses is the median. One-half of all respondents will be below this value, while one-half will have a higher value. The median also is known as the 50th percentile. The advantage in using the median is that it is not affected as much by extreme highs or lows in the range of values, as is the case with the mean.

The central value in a group of ranked data â€“ useful for ordinal-level data. On some occasions the median may be a 'truer' reflection of the norm than the mean â€“ for instance average income is usually a median, since the mean is distorted by a few people with very large salaries.

The median is the middle value of observations arranged in order of magnitude. (from the BRFSS site http://www.cdc.gov/brfss) Represents the actual number of observations in a sample such as responses to a survey questions.

An estimate of the center of the distribution of the data. It is the value above and below which lie an equal number of data values when the data are arranged in increasing or decreasing order. If the count of the sample is odd, the median is the middle value. If the count is even, the median is the average of the two middle values.

The middle number in a list of ranked numbers arranged in ascending or descending order. In the state of Illinois (excluding Cook County), the median level of assessment is 33.33% or 1/3 of Fair Market Value.

The value that represents the point at which there are as many instances above as there are below (e.g., the "median" of a group of persons earning 3, 4, 5, 8, and 20 dollars a day is 5 dollars (note: the average is 8 dollars)).

A measure of central tendency. It is the middle observation; i.e., the one that divides the distribution of values into halves. It is also equal to the 50th percentile.

Here are two accurate definitions for this term: "The median is the middle value in an ordered sequence of data. If there are no tied (equal) values, half of the observations will be smaller and half will be larger than the median. The median is unaffected by any extreme observations in a set of data" (Reference: Applied Statistics: A First Course, M. L. Berenson, D. M. Levine, D. Rindskopf, 1988 Prentice-Hall Inc., p. 40)."The median is employed with ice statistics due to the ordinal nature of the ice attributes. For example, 9+/10 ice concentration is greater than 9/10 concentration and first-year ice is greater (thicker) than grey-white ice." (Reference: Sea Ice Climatic Atlas*, East Coast of Canada, 1971-2000. 2001, Kaice-Tec Reproduction Ltd., p. 7).

The middle point in a set of data. Defined as the number relative to which half of the scores are greater and half of the scores are lower.

The number that lies in the middle when a set of numbers is arranged in order. If there are two middle values, the median is the mean of these values.

The middle of a group of measurement values when arranged in numerical order. For example, in the group (32, 45, 78, 79, 101), 78 is the median. If the group contains an even number of values, the median is the average of the two middle values.

The mid-point of a distribution where half of the sample are less than or equal to the median and half of the sample greater than or equal to the median.

(3) The middle value in a set of data when the data are listed in order from smallest to largest (or largest to smallest). If there is an even number of data points, the median is the mean of the two middle values. Example: 2, 3, 4, 6, 10 - the median is 4 because it is the middle value.

(1) The statistical median, which is an order statistic that gives the "middle" value of a sample. (2) A triangle median, which is a line segment from one of a triangle's vertices to the midpoint of the opposite side.

A number which is half way between the lowest and the highest in a set of numbers Development Leadership Network, Success Measures Guide Book GlossarySource web site

Statistical measure of central tendency in a set of data. The median is the value halfway through a data set where the values have been ordered from lowest to highest. In an even data set, the median is the average of the two halfway values.

The middle value in a sample, whereby half of the values are above it, and half are below it.

The value (rate of return, market sensitivity, etc) that exceeds one-half of the values in the sample and is exceeded by the other half. The median is always the middle value, as distinct from the mean, which represents the average value. For example, if five items cost £20, £80, £100, £300 and £500 respectively, the median value would be £100, whereas the mean or average would be £200.

A statistical term representing the middle value of a series of numbers when the numbers are arranged in order of their numerical quantity or value. Equal numbers of data points can be found that are greater than or less than the median. For example, in the sequence 1,3,4,7,8,10,12, the median is 7.

The middle number in a defined distribution; when looking at estimates, median refers to the estimate above and below which lie an equal number of estimates for the period indicated.

The midpoint of the range numbers that are arranged in order of value.

In statistics, the quantity designating the middle value in a set of numbers that are either in increasing or decreasing order. If there is no middle number, it is the average of the two middle numbers. Examples:The median of the numbers 1, 1, 2, 4, 5, 6, and 7 is 4. The median of the numbers 1, 1, 2, 4, 5, 6, 7, and 7 is4.5.

This measure represents the middle value (if n is odd) or the average of the two middle values (if n is even) in an ordered list of data values. The median divides the total frequency distribution into two equal parts: one-half of the cases fall below the median and one-half of the cases exceed the median. (Census)

One form of the average. The middle item in a ranked order.

The middle value in a set of numbers arranged in increasing order. If there is an even number of values, then the median is the average of the middle two values. For example, the median of the set {10, 12, 14, 19, 20} is 14. The median of the set {2, 3, 4, 6, 8, 9} is 5, which is the average of 4 and 6.

the middle number in a data set, with an equal number of data points of lower and higher value.

moving average noise

Not to be confused with average (or mean), the median is found by arranging all the numbers in a set, and choosing the middle number. If the set has an even amount of numbers, then the median is the average of the two middle numbers.

The midpoint in an array of sequentinally ordered numbers.

measure of central tendency that corresponds to the middle score.

The value in the middle of a collection of ordered data. In other words, the value with the same number of items above and below it.

the middle value, as opposed to the average value

The midpoint. If eighty-one patients were treated with drug XYZ, and the time for white blood cell counts to recover following this treatment ranged from two to sixty days, after you rank the patients by the number of days required for their white blood cells to recover, the median is the number of days that it took patient number forty-one's white blood cells to recover.

Strip of land that separates the lanes of opposing traffic. Alternately, the midpoint in a range of numbers.

In geometry, a median of a triangle is a line joining a vertex to the midpoint of the opposite side. It divides the triangle into two parts of equal area. The three medians intersect in the triangle's centroid or center of mass, and two-thirds of the length of each median is between the vertex and the centroid, while one-third is between the centroid and the midpoint of the opposite side.

An extended reserved area at, or close to, the centre of the carriageway which provides a place for pedestrians to wait before crossing the next part of the road.

An island in the center of the roadway that provides pedestrian refuge and reduces the distance between safety points. A median may also be used as an area for light rail or bus rapid transit stations.

An island in the center of a street or intersection to protect pedestrians and provide landscaping. Medians prevent passing, and left turns, separate opposing travel lanes and provide visual enhancement.
