Methodology and work approach

At Opinòmetre we work with a rigorous methodological approach, adapted to each project and focused on generating reliable information for strategic decision-making. We combine quantitative and qualitative techniques, integrating solid data collection processes, advanced analysis and the production of applied reports. Our working model covers all phases of the study: methodological design, data generation, technical analysis and the presentation of clear, structured and actionable results.

Quantitative data generation

We apply quantitative techniques aimed at obtaining structured and representative data that allow robust statistical analyses.

01

Face-to-face surveys (CAPI)

Face-to-face surveys assisted by electronic devices. They allow greater control of the interview and are suitable for complex questionnaires or audiences with lower digital access.

02

Telephone surveys (CATI)

Computer-assisted telephone interviews. They ensure speed, fieldwork control and wide geographical coverage with automated quality control.

03

Online surveys (CAWI)

Self-administered online questionnaires. An agile and efficient method for large samples and audiences with digital access.

04

Postal surveys

A traditional method used in specific studies where a physical format or access to certain groups is required.

05

Hall test

Product tests carried out in controlled environments to assess perception, acceptance or direct experience.

06

Home test

Product evaluation in the consumer’s usual environment to measure real use and natural behaviour.

Qualitative information generation

Techniques aimed at understanding deep motivations, attitudes and perceptions that cannot always be captured through structured surveys.

Focus Groups

Moderated group dynamics that allow exploring collective opinions, attitudes and discourses on a specific topic.

In-depth interviews

Structured or semi-structured individual conversations to analyse personal perceptions and experiences in depth.

Projective techniques

Tools that help identify latent attitudes and unconscious perceptions through indirect stimuli.

Experimentation

Design of controlled scenarios to assess behaviour and response to different variables.

Observation

Systematic analysis of behaviour in real environments without direct intervention.

Mystery Shopping

Anonymous service evaluation to measure service quality and the actual user experience.

Quantitative statistical analysis

We apply advanced statistical techniques that allow data to be interpreted with scientific rigour and solid conclusions to be obtained.

01

Descriptive statistics

Production of tables, charts and measures of central tendency, dispersion and shape to describe the information collected.

02

Exploratory analysis

Preliminary techniques to identify patterns, trends and possible relationships between variables.

03

Inferential statistics

Construction of confidence intervals, hypothesis testing and sample design that allow results to be generalised to the population.

04

Correlation and cross-tabulation

Analysis of relationships between variables and segmentation of results.

05

Regression analysis

Modelling of causal relationships between variables in their different forms (linear, logistic, etc.).

06

Multivariate analysis

Principal components, factor, discriminant and cluster analysis to identify complex structures in the data.

07

Advanced models

Structural equation models, multilevel analysis, time-series analysis and survival analysis for more complex studies.

Advanced qualitative analysis

Structured interpretation of discourse and social context using specific comparative analysis techniques and mixed methodologies.

Contextual analysis

Study of context, narrative and meaning-making in the collected discourse.

Delphi method

A structured consultation technique with experts to reach consensus in complex scenarios.

QCA (Crisp and Fuzzy Set)

Qualitative comparative methods that allow the analysis of causal configurations in complex social phenomena.
