[Latin mediānus, from medius, middle.]

medianly me'di·an·ly adv.

If a set of numerical data has n elements and is arranged in order so that either

, then the median is


if n is odd, and


if n is even.

For example, the time intervals (in minutes, to the nearest minute) between the eruptions of Old Faithful on 1 August 1978 were 78, 74, 68, 76, 80, 84, 50, 93, 55, 76, 58, 74, 75.Arranging these thirteen values in order, we get 50, 55, 58, 68, 74, 74, 75, 76, 76, 78, 80, 84, 93,to give a median of 75 minutes. For 4 August 1978, there were fourteen inter-eruption times, which arranged in order were 60, 66, 67, 68, 70, 72, 73, 75, 75, 75, 79, 84, 86, 86,so that the median is ½(73+75)=74.

Alternatively, an approximate value for the median can be read from a cumulative frequency graph as the value of the variable corresponding to a cumulative relative frequency of 50%.

For a continuous random variable X, the median m of the distribution is such that P(X≤m)=½. For a discrete random variable taking values x₁<x₂<..., the median is x_i if P(X<x_i)<½ and P(X>x_i)<½, and it is ½(x_i+x_i+1) if P(X≤x_i)=½ and P(X≥x_i+1)=½. See also percentile; quartile.

(mē'dē ən)
adj

1. pertaining to the middle. n 2. a measure of central tendency attained by a calculation or count that separates all cases in a ranked distribution into halves. The median may be used as an average score.

In a set of data arranged according to rank, the median is the central value. Thus, for the data set: 1, 2, 3, 4, 5, the median is 3. If there is an even number of values, the median lies midway between the two central values. Thus, for the data set: 1, 2, 3, 4, 5, 6, the median is 3.5. For grouped data, the median is found by plotting the data on a cumulative frequency curve. The median value occurs halfway along the y-axis of cumulative frequency: at 50%.

1. Statistic derived from the middle value in a frequency distribution on either side of which lie values with equal total frequency. It is the middlemost score of a series arranged in rank order.

2. In anatomy, applied to a structure in a central body position, or situated towards or in the plane that divides the body or body part into left and right halves.

In statistics, the middle value of a set of numbers or data points; half the figures will fall below the median and half above. (See average; compare mean and mode.)

The point in a series at which half of the values or units of the series are higher and half lower.

1. situated in the median plane or in the midline of a body or structure.
2. the perpendicular line that divides the area of a frequency curve into two equal halves.

• m. calving date — the number of days between the first calving in the herd and the 50th percentile calving; an excellent measure of fertility status of seasonally calving herds; in dairy herds the target is 18 days.
• m. eminence — part of the hypophysis.
• m. nerve
• m. nerve block — the anesthetic agent is injected on the medial aspect of the forelimb, just distal to the elbow. An area encircling most of the fetlock and pastern is desensitized.
• m. nerve injury — results in overextension and dropping of the carpus.
