STATISTICAL RESEARCH STAGES

1. ¿What is statistics?

   • The word statistics refers to a system or method used in the collection, organization, analysis and numerical description of information. It can also be said that statistics studies the behavior of events or group phenomena. Martínez Bencardino, C. (2018) p.23
     • Descriptive or Deductive Statistics
       • It is limited to the description of a set of data without reaching conclusions or to generalize about a larger group.
     • Inductive Statistics or Inference
       • It involves analysis whereby you try to reach conclusions about a larger group or population, based on information from a smaller group or sample.

2. The statistical elaboration process is divided into six (6) phases:

   • Planning or preparation
     • All data collection requires planning that defines the aspects that are going to be covered, how it is going to be done, and resolves any difficulties that may arise.
   • Harvest
     • The subsequent result of the statistics depends on this task. This can be considered the most important part of statistics since the result of the investigation depends on it. And this can be done by various systems; It includes from the preliminary data to the final data.
       • The collection stage comprises several aspects: Martínez Bencardino, C. (2018). p.50
         • - The collection itself.
         • - Control of the number of forms collected.
         • - Control over the quality of the information collected.
   • Criticism and codification
     • All the material collected during the investigation must be evaluated and processed before being approved, the objective of this is to verify that the material meets the necessary and required conditions to be used in the investigation.
   • Analysis and interpretation (numeric and graphic)
     • The information is analyzed and interpreted based on the objective of the investigation and the established hypotheses.
   • Publication
     • Final phase of the investigation, through which the result of the investigation is shown to interested persons, taking into account that the information is understandable.
   • Processing
     • It is about processing the information collected during the investigation to later be processed through different mechanisms (manual, mechanical or computerized)
