Probability & Statistics Stage 1

On this scale, 0 is a value that indicates the absence of the measured characteristic. For example age, weight, etc.

Scale where data is indicated with a relative position, with an order either from lowest to highest or vice versa.

Science responsible for collecting, organizing, interpreting data to draw conclusions from it.

Variable represented numerically, for example weight, age.

Scale where data is represented by magnitudes and equal distance between the scale values. 0 doesn't mean lack of value.

Planned and controlled procedure used in scientific research to obtain information about the behavior of a process.

To measure a variable is taken as a reference.

Sample where isn't obtained by a random selection process, but the criteria or judgment of the person.

Responsible for the collection, organization, presentation, and analysis of data of a specific population.

Responsible for analyzing the information presented about certain population to draw conclusions and make decisions.

Type of population in which is possible to list its elements due to the knowledge of its size.

Type of graphic representation

Sample where elements of the population have the same probability of being selected

Type of graphic representation

Individuals representative of the population from which inferences are made. Selected with a specific technique.

Type of graphic representation

Variable whose values are natural numbers. For example, the number of siblings for each student in a group.

Variable that represents non-numeric qualities, attributes, etc. For example maritual status, profession.

Each one of the elements belonging to the population, which can be measured or qualified.

Value obtained for each individual in the population according to the variable that is set for measurement.

Most widely used instrument for collecting data; set of questions regarding one or + variables to be measured.

Set of individuals on which the study will be carried out.

Variable that can only take two values such as: yes-no, 1-0.

Type of population in which the numbers of elements aren't known and cannot be counted.

Variable whose values are represented by real numbers and can take any real value within a range: for example height.

Consists of obtaining data by consulting available sources of information (books, internet, files).

Type of graphic representation

Scale where data is tagged for identifying and sorting, without an order of preference. For example: profession.

Type of graphic representation

Characteristic of the population/sample whose measurement can change a value. Represented by letters of the alphabet.
