– Surveys & Sampling

Organizations improve performance and accelerate planned change through designing and conducting surveys on opinions, cultures, behaviors and practices.
Over the years, Analytica had the opportunity to conduct surveys with many industry leaders, and we bring to each project what we have learned, customizing our approach to match the individual culture and dynamics of each client we serve.
We design, conduct and analyze open and closed surveys, over internet, telephone or face-to-face channels.
Internet surveys are usually constructed with the industry-standard Limesurvey online survey system. Telephonic surveys are executed through our global partners, and face-to-face surveys are executed via a number of local partners. Paper surveys are also possible, where questionnaires are filled-in by the surveyed population or through our partners, and re-encoded at our premises.
Survey design is made in a statistical correct and strict way. Many standard or customized processes are possible.
We combine the assistance of a survey expert with tangible survey tools and aids to give you the skills to implement higher-quality surveys, especially in the area of improving questionnaire design.
We provide targeted assistance on survey projects from design tp statistical analysis and we can build and create a survey project with complete execution, customized from start to finish to meet your needs.


We conduct  local  (corporate level, neighbourhood, regional or domestic) surveys or abroad using best-practice approach. We apply a practical, solid, statisticaly sound methods for conducting surveys.

We help in the design and conduct of surveys. We organize and plan the surveys and work with our partners for the execution of face-to-face and telephonic surveys (“enquetes”, “peilingen”) for small or large organizations, and for governmental/NGO’s.

We apply the best practices of market research, sampling in many industries.

One of the main benefits of using a third party company for conducting surveys and the analysis is to ensure the anonymity of the surveyors (eg: in the case of surveys targeted to employees of a company).



Survey target groups:

The correct determination of the sampled population is important.

  • Consumers
  • Patients (healthcare service and products consumers)
  • Workforce and Employees (HR)
  • Population (public governance, NGO’s, demographic institutes, federations, academics, …)


Industries and Activity Domains

Surveys are conducted using appropriate communication channels by topic or project:

  • Healthcare. Surveying the choice of a children hospital, surveying the mid-term perception of a hip replacement. Many topics are possible
  • Perception and market reactivity measurement of your services or product
  • Sales behavior of products or services (telecom products, hospital services, retail and distribution, TV audiences, etc…)
  • Public. Demographical, economical, voting tendencies, etc…


Weak sampling plans generate unreliable results. The sampling method optimizes quality and reliability.

  • Random Sampling and Systematic Sampling
  • Stratified Sampling
  • Cluster Sampling
  • Regression or Ratio Sampling

In example of the healthcare sector, we separate surveys in two families, depending on the final goal of the survey:

  • Healthcare Marketing: measuring the perception of the consumers and referring doctors
  • Quality management: measuring the level of quality of all aspects of the medical prestation as perceived by the patient

 Stratified Sampling
