Steps to start a statistical research

Steps to start a statistical research

1. It is a statistical method that uses analysis and allows to collect, order, classify and quantify a series of data.

2. planning

   • It is a previous establishment that allows detailing the aspects that the investigation will cover.
   • Research objective
     • Define the purpose of the investigation
       • Allows you to identify who is being investigated
         • Element
         • Unit
     • Determine its quantitative and qualitative nature
       • Allows you to investigate qualitative aspects
         • It can be registered by numbers
       • Allows you to collect qualitative data
         • Surveys and literary annotations
     • Determine the feasibility of the investigation
       • You need to examine whether they can be accurately known
         • They externalize
         • Can be counted
         • Admit its existence and its intensity
     • Determine the feasibility of the investigation
       • Limits the very object of the investigation
         • Limit the field of investigation.
         • limit the space
   • Purpose
     • Know the reality in an observation
       • Link two or more phenomena
       • Determine the causes of the phenomenon
       • a conclusion is reached
   • The source of the information
     • direct
       • Data is collected from events of any kind
         • Its presence or absence and its intensity are observed and recorded by means of a number
     • Hint
       • It is investigated in statistics, in different facts, to later deduce the value that you want to know
     • primary source
       • when information is obtained directly from research
       • secondary source
         • The information is complementary.
   • Procedures
     • Clarity
     • Simplicity
     • Utility
   • Material
     • Instruments to carry out an investigation
       • printed matter
         • Questionnaires, bulletins, registration forms, registration, circulars
       • Form
         • Allows annotating responses of the echo that is investigate.
           • Collectives
             • multiple units
           • Individual
             • a single unit
   • Budget
     • Understand the cost and its financing
       • Organization
       • Field work
       • Systematization
       • Publication

3. Harvest

   • Collect the basic data material of the facts investigated
     • Collection techniques
       • Direct observation
         • Interview
       • Poll
       • Questionnaire
   • Distribution of the material Collection instrument
   • Collection proper
   • Control of miners of collected formulans
   • Camural on the quality of the information collected
   • Can be done by various systems
   • Control the data
   • Organize

4. Organization

   • Organization and classification, thus facilitating representation in tables, charts and graphs
   • Validity of the results
   • Conclusions depend on the reliability of the results used

5. criticism and coding

   • It is a set of review and correction operations of the information collected, which allows us to group and process it, in such a way that it facilitates the elaboration of tables, graphs and analysis, necessary in the publication. (Martinez, 2012, p: 29)
     • Classify the primary material that comes from the same research, into three groups:
       • Good material
       • Incorrect but correctable material
       • Incorrect or disposable material

6. Tabulations or procedure

   • It is an important part that integrates the general planning of the investigation
     • Manual
     • Mechanics
     • Computerized
     • Number of forms to be used.
       • Number of questions in the form.
       • Time and resources, either financial or equipment available

7. analysis and interpretation of results

   • It is considered important in the report, since the analysis of the data will have to do with the formulation of the objective of the investigation.
   • Professor Jon W. Best suggest
     • Problem
       • It is clearly established
       • It is well defined
       • Its meaning is recognized
       • The questions are specific and clear
       • Assumptions and limitations are established
       • Important terms are defined
     • Review of the related bibliography
       • Adequate amplitude
       • Important findings highlighted
       • It is well organized
       • Get an effective summary.
     • Procedure used
       • Describe the experimental design in detail.
       • Suitable design
       • Describe the samples
       • Recognize relevant variables
       • Recognize relevant variables
         • Adequate controls
         • Suitable data collection instrument
         • Validity and reliability
     • Data analysis
       • Proper use of tables and figures
       • Concise and clear exposition of the text
       • is logical and perceptible at analysis of
       • Data relationships
       • Analysis of data
       • Accurately interpret statistical analysis
       • Summaries and conclusions
         • You reframe the problem
         • Procedures are described in detail
         • The findings are presented concisely.
   • Qualification
     • Clear and concise
     • Does not promise more than the study can provide

8. Publication

   • Final phase of the investigation contains:
     • Problem Statement
     • Research objective
     • Hypothesis to be tested
     • Brief description of the methodology adopted, design and sample size
     • A copy of the form used in the collection and the questions considered most important in the investigation may be included in the report.
