steps to start a statistical research

steps to start a statistical research

1. planning

   • problem planning
     • Define the nature of the problem
     • Justify the investigation
     • Determine the general and specific objectives
     • Define terms to use
   • bibliographic study
     • It consists of finding out who has carried out studies on the same subject, in order to use their results if the research was good enough and is adapted to the time and our objectives, saving time and money in these conditions.
   • methodology
     • Define the population
     • Sample selection
     • Design of forms and instructions
       • Identification data
       • Specifics of the problem
   • design of collection plans
     • the number of collectors that will be needed, an instruction manual, whether field supervisors are necessary or not, try to foresee solutions to possible difficulties that may arise during their work.
   • research evaluation
     • It is about comparing what was planned with what was executed during the research process and establishing the reasons for the differences to capitalize on the experiences in other future research.

2. collection

   • Data collection is a necessary phase prior to conducting a statistical study. This is because these data are required for the processing of the information and its subsequent interpretation.
   • also
     • its value as a means of control, since its distribution and its peculiarities indicate the quality of the material (forms), the essential personnel, the convenient advertising, the choice of information source, and the procedures to be followed in the systematization of data.
   • The collection stage includes several aspects such as:
     • distribution of the collection material or instrument
       • the collection itself
         • control of the number of forms collected
           • control over the quality of information collected

3. organization

   • there are two tendencies
     • centralization
       • it is unquestionably necessary in the technical order. the technique, the general rules, the direction of all research must be central to everything.
     • centralization
       • It must be used in the administrative order, in the executive order, to select personnel, to collect data, to, finally, serve as an intermediary between the various dependency categories
   • There are three ways to ORGANIZE information
     • tabulation
       • graphing
         • parameters

4. analysis

   • Statistical data analysis is a procedure for performing various statistical operations.
     • Statistical research analysis consists of five basic principles:
       • tools
         • sample size
           • Regression
             • Main Measures
               • Standard deviation
     • Also, it recognizes two types of very important data
       • quantitative
         • continuous data and discrete data
       • qualitative
         • Binomial Data, Nominal Data and Ordinal Data

5. presentation of results

   • A good presentation of results must be visually simple. Shows conclusions and relevant information for decision making.
   • most relevant elements of a results report:
     • From the macro to the micro
     • Only strategic indicators
     • Reliability and comparability of information
     • visual simplicity
     • Conclusions instead of data
     • Drill down when necessary
