    This depends on how you define the median. If a distribution has probability one on a single point, then that is the median, and it has a probability greater than [math][/math], [math]1[/math].

The geometric median of a discrete set of sample points in a Euclidean space is the point minimizing the sum of distances to the sample points. This generalizes the median, which has the property of minimizing the sum of distances for one-dimensional data, and provides a central tendency in higher dimensions. It is also known as the 1-median, spatial median, Euclidean minisum point, or.

A nonlinear integer programming formulation is developed, and a linearization with number of variables and constraints proportional to the number of sites, cubed, is by:   This chapter analyzes the ordered median location problem in three different frameworks: continuous, discrete and networks; where some classical but also new results have been collected.

For each solution space we study general properties that lead to resolution by: 7. sequences, logic and proofs, and graph theory, in that order. Induction is covered at the end of the chapter on sequences.

The Arithmetic Median of the given numbers is In case of a group having odd number of distribution, Arithmetic Median is the middle number after arranging the numbers in ascending order.

Example. Let's calculate Arithmetic Median for the following discrete data. We shall also discuss a few properties of Median. Median for Discrete and Continuous Frequency Type Data (grouped data): For the grouped frequency distribution of a discrete variable or a continuous variable the calculation of the median involves identifying the median class, i.e.

Ask Question Asked 5 years, 7 point a)To determine the median of a discrete statistical series: It stores values of the variable in ascending order.

When the total number N is odd, the median is the value of the series of row (N+1/2) When the total number N is even, the median is the half sum of the ranks (N/2) and (N/2 +1.

The following diagrams show how to obtain the median from a given set of data. Scroll down the page for examples and solutions. Given a set of observations, the median is the middle value among the observations.

To find the median, you must first arrange the observations in an ascending (or descending) order. this problem, and we will rst consider a speci c type of a discrete location model. These are models in which the facilities and demands are in discrete positions. The p-median problem is a speci c type of a discrete location model.

In this model, we wish to place p facilities to minimize the (demand-weighted) average distance between a demandFile Size: 95KB. Find answers to Median for continuous and discrete data.

Median is the most middle value in the arrayed data. It means that when the data are arranged, the median is the middle value if the number of values is odd and the mean of the two middle values if the number of values is even.

A value which divides the arrayed set of data into two equal parts is called the median, and the values greater than the median are equal to the values smaller than the.

This works for continuous distributions, but for discrete distributions median would almost always be undefined if we were using this definition. How is it defined in the discrete case.

An instance of a p-median problem gives n demand points. The objective is to locate p supply points in order to minimize the total distance of the demand points to their nearest supply point.p-Median is polynomially solvable in one dimension but NP-hard in two or more dimensions, when either the Euclidean or the rectilinear distance measure is this paper, we treat the p-median problem Cited by: The p-median problem is central to much of discrete location modeling and theory.

While the p-median problem is NP-hard on a general graph, it can be solved in polynomial time on a tree. A linear time algorithm for the 1-median problem on a tree is described. We also present a classical formulation of the problem.
