Opinion Studies

The most used techniques are te following:


Appropriate to know quantifiable aspects of consumption, habits y the market, as well as the attitudes through scales, by answering the questions: what, how many, when, how long…?

A representative sample of the de la population, between 400 and 2000 interviews (depending on the requested accuracy), allows to obtain representative data through statistics.

• Telephone

Phone interviews, assisted by computer (CATI system), are based on the fact that almost 100% of the households do have mobile phones and 82% landline phone. The interview is directly recorded and that allows a very fast data gathering. The cost is lower than the personal interview.

• Online

Interviews through panel or surveys promoted on the Social Media. Recommended to access the younger than 65 population, having a high internet usage. Also very useful to investigate users of a specific web.

• E-mail

When it comes to a specific population and e-mail addresses are available. For example, one institution, a company or people who have voluntarly signed up for a data base.

• Personal

At home, at point of sales or at headquarters. They are more expensive studies because they require the interviewers to travel.

• Postal mail

Not recommended due to low response rate.

The quantitative technique is widely used in most of opinion studies.


The qualitative analysis is aimed at knowing the motivations of the consumers and their attitudes towards products or institutions. These techniques allow collecting data that answer the questions: What? Why? How? It is about knowing the causes of behaviours and the factors that influence the decision-making.

The main quantitative techniques are the interview and the group meeting. Both can be done in person and over the phone or online.


Given the extensive data base that already exist on most of the research topics, they are used, when considered reliable, as a source of documentation or for potential comparative analyses over time.
