In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmax x i P(X = x i)).
The median of a Cauchy distribution with location parameter x 0 and scale parameter y is x 0, the location parameter. The median of a power law distribution x −a, with exponent a > 1 is 2 1/(a − 1) x min, where x min is the minimum value for which the power law holds [10]
The National Institute of Statistics and Geography (INEGI from its former name in Spanish: Instituto Nacional de Estadística, Geografía e Informática) is an autonomous agency of the Mexican Government dedicated to coordinate the National System of Statistical and Geographical Information of the country.

Some examples of statistics are: "In a recent survey of Americans, 52% of women say global warming is happening." In this case, "52%" is a statistic, namely the percentage of women in the survey sample who believe in global warming.
A probability distribution is a function that assigns a probability to each measurable subset of the possible outcomes of a random experiment, survey, or procedure of statistical inference.
When full census data cannot be collected, statisticians collect sample data by developing specific experiment designs and survey samples.Statistics itself also provides tools for prediction and forecasting through statistical models.
For the 1-dimensional case, the geometric median coincides with the median.This is because the univariate median also minimizes the sum of distances from the points. (More precisely, if the points are p 1, ..., p n, in that order, the geometric median is the middle point (+) / if n is odd, but is not uniquely determined if n is even, when it can be any point in the line segment between the two ...
