methods

  • Manipulative-experimental tradition:
  • nomothetic approach: Search of general laws of behavior.
  • The independent variable/s are manipulated to see their/its impact on the dependent variable/s.
  • Determination of causal relationships.
  • Laboratory research controlling for confounding variables.

Research methods and design
  • Correlational-associative tradition


  • Idiographic approach: Evaluation of differences between individuals or groups.
  • Determination of correlations/associations between variables or factors.
  • Field research.
  • Main types of non-experimental research:
  • Survey methodology.
  • observational methodology (case studies).
  • Qualitative Methodology (e.g., interviews).

Research methods and design
  • Survey methodology:
  • Its aim is to describe characteristics of a population fromresponses to surveys or questionnaires.


  • Observational methodology:
  • Its aim is to describe phenomena occurring in natural environments. It is a systematic record of behavior.


  • Qualitative Methodology:
  • Its aim is to describe a phenomenon seeking more meaning than quantification.

Research methods and design

Experimental or quasi-experimental methodology:

The most common techniques of data analysis

consist contrast of means: t-test, ANOVA, etc.

Correlational methodology:

Pearson coefficient, or association, such as as χ2, egression models in which one or more factors are explained are also used from a mathematical function based on other variables or factors (single or multiple linear regression, logistic regression, etc.)

Data analysis, interpretation and evaluation of results.

The last step of any scientific research is the dissemination of the findings so that it is shared with the scientific community.


  • If there is no diffusion, the research is unknown and therefore with no real impact
  • How can we do that?

  • • Congress: Oral presentations / Posters

    • Scientific journals:



    - Impact Index: Journals with more impact (Q1).
