Statistical Engineering


Career Objectives

The mathematical study of processes which response is not possible to determine accurately, or events in which there is no certainty that they will occur; in order to help make decisions about them.


Professional Profile

-Professional in mathematics qualified in data analysis, the use of *statistical procedures and computer tool to efficiently support decision making under uncertainty conditions, in different fields of the social, economic and productive activity.

He works with professionals from other areas, related to the management of large data volumes, in order to explain, solve and/or predict a phenomenon.

He applies statistics to scientific, industrial or social problems. For that, it is necessary to collect and record data and obtain their patterns in order to describe their characteristics and build a *statistical model, which will be the information base for decision making.


Specific tasks or activities carried out in the profession

He designs, plans and organizes censuses and statistical surveys.

In censuses, he operates statistically on the total population, meanwhile in statistical surveys, he operate on a *sample of the population from which he makes estimates regarding the population, showing margins of error of said estimates; this way he obtains very similar results to those he would get from a study of the entire population, but at much lower cost.

In the statistical study, he performs the following process:

Problem Statement

He lays out the problem to be studied, setting the objectives or questions, such as: which will be the mean (average) of this population with respect to that characteristic? Example: what will be the mean of the young population in relation to drug use?, Is there any relationship between this and that variable? Example: What relationship will there be between the economic income level and the level of drug use in the youth population?

Besides, he analyzes the means available to carry out this research and the procedure to be followed.

Sampling

He determines and administers the obtaining of a *sample of data from the *population, so that this sample is *representative of said population. For that, he must apply *sampling or data collection techniques.

Example: A representative group of the youth population is consulted regarding their drug use.

Data Processing

In this stage, the sample is filtered by deleting possible errors; the data are analyzed and summarized.

Data can be summarized numerically or graphically, from which statistical *parameters are obtained. One of these parameters is the arithmetic mean (average) and the *standard deviation or degree of dispersion.

Example: a sample with x average frequency of drug use; its dispersion is analyzed, that is, to know if this average is produced because most have that consumption of consumption (low dispersion) or this average occurs because a few have a very high frequency of consumption and the rest is very low (high dispersion).

Basically, it is about a series of measures of central tendency, to see how data is grouped or scattered around a central value.

From this statistical study of data, information of the characteristic studied is obtained, such as: its existence, location, distribution and value.

He interprets (the meaning) the statistical data and prepare them for publication.

Estimation of Population Parameters

He studies the *probability of occurrence (frequency in which the fact is repeated) of the *sample information and, based on that, he creates models (*statistical models) of the behavior of the event that is being studied, showing the probability that this event occurs in the whole population.

(Example: probability of occurrence of drug use in the entire youth population).

Based on the *statistical model, he *infers regarding the population, providing the margin of error of those inferences.

For instance: from the study, he concludes which fraction of young people in the youth population use drugs and the margin of error of this estimation.

He investigates, perfects and develops statistical *theories, *methods and *techniques.

He advises on various data collection methods.

He advises on statistical *methods and *techniques.

He creates his own instruments or adopts the existing ones to face the problems he addresses.

He advises on the study of information in fields and disciplines such as economics and management, medicine and other fields of the exact, biological, and natural or social science.

He leads multidisciplinary teams responsible for decision making in conditions of uncertainty and risk such as opinion and market *surveys, production efficiency studies, risk analysis in the insurance area.

In the practice of his profession, he uses modern *calculation and telecommunication techniques.
