Surveys on products from the market

Within the implementation of the opinion polls to marketing and market research prominently occupy surveys on products.
A survey of product, as part of a plan of marketing of a company or a more general market study, usually only one cog in the processes of research and decision-making process of a company, but they can - of course - be analysed separately.
We will mention some common survey carrying out market research on products sold.

• Pilot surveys on new products. Here, there are innumerable variants, some of which are true social experiments, and which can be combined with the display, tasting, etc. of products as well as quantitative studies.


• Surveys on the concept of a service, product: meaning, social representations to generate conscious and unconscious associations.


• Brand-product surveys: new marcas-producto, variations in branding or analysis of changes in the perception of the consumer of a brand-product.


• Surveys on acceptability of products: new products, variations on the same product.


• Surveys on packaging: the presentation changes, changes in content, slogans, in the amount of product. They can be of acceptability or preliminary investigation of changes in packaging, or changes in course.


• Survey on marks independently of products and his names. Surveys about products or services: marks internet, naming, slogans, social representations of consumers and customers linked to the product.


• Surveys on sales and distribution: on the structure of the sale of the product, on points of sale, how to sell it.

These are some typical ways in which surveys public - not, but customers, users or consumers of products - can be used in research of market or marketing products.

Surveys and accidental sampling

Opinion polls carried out by accidental sampling of the survey is not random.

Accidental sampling are characterized method is selected without the person being surveyed, cases are chosen to have at hand.

Examples of accidental sample surveys are what make the radio and television journalists.

These surveys are not representative and can never know how reliable the sample is selected.

As a research about public opinion is unreliable.

Provided that presents the opinion of the way we run a double risk of having a biased sample.

First, as the sample is casual, may not be at all representative, and even that interested people try to be surveyed.

In that case, the bias of the sample increases.

But secondly, if the survey is planned or executed from a media or institution with a clear profile or defined interests, who agree to be interviewed by such means shall be persons of similar ideological.

An example of this is the surveys of online newspapers, where readers vote who they are, a universe is clearly not representative.

Survey and research and as an instrument of data collection.

One of the difficulties of providing a definition of what a survey is, first, a survey called two different things in the investigation.

Survey is called the method or technique to relieve data using an instrument such as the questionnaire and survey procedure is called to make a quantitative social research using a questionnaire.

It may seem the same but it is not. If a researcher wants to supplement a social study of public opinion or qualitative data and is a project developed with defined assumptions and other data already obtained, in that case if it decides to conduct a survey is merely using a data record.

In this respect the survey is similar to a camera or microscope, bridging the gap.

However, if the investigator made another quantitative study from scratch, and should pose variables, defining units of analysis, sample design, develop scales to measure attitudes, determining a permissible error, and a questionnaire survey may call the whole investigation.

Opinion Surveys or Opinion Polls?

There is an ambiguity about whether we should speak of opinion surveys or opinion polls either.
That is, if both terms are synonymous.
But in reality they are not, because although what defines an opinion poll is correct when predicated of an opinion poll, the converse does not hold.
A poll is a survey research, but social. In contrast, a sample survey can be done to obtain information about the behavior of the stars or the characteristics of books in a library.
In other words, there are surveys that are not of opinion, while no research surveys that are not polls, agreed to call for polls to quantitative studies through surveys.
Although it is possible to do an opinion poll.
Moreover, "survey" is called to the technique of data collection, but also the result of completing a questionnaire.
Issues to be considered not to confuse the meanings and know well what is spoken.

As conceived opinion survey

As conceived opinion survey

When planning or designing an opinion survey is essential to note here:
1) choose the universe to be surveyed
2) define the statistical unit or unit of analysis Stats
3) collect information to organize the opinion survey, classify and organize
4) choose the method or data collection technique, the type of survey (individual, personal, phone, email)
5) choosing the sampling method (random, quota, cluster, etc.).
6) define the variables to be analyzed and the type of statistical analysis will be done with data from questionnaires
7) establish the sample size
8) define a sampling error according to relevant factors such as budget, time and type of sampling design
9) establish the economic cost of the survey and total execution time of the investigation
10) organize the field work calendar, staff and resources.

Two types of political surveys: pre-election and voting intentions

In the pre-election survey is usually evaluated trends, opinions and attitudes related to the assessment of both policies and actions of government and with certain people.
In the first case, the pre-election survey can evaluate public policies, or the possible impact on public reform or specific action.
In the second pre-election survey seeks to know where certain personalities are known and candidates.
In contrast, pre-election survey seeks eminenemente know if people would vote, not vote or do not yet know, a particular candidate.
It is characteristic of pre-election poll people to try to know as a candidate associated with certain characteristics, such as being honest, experienced, tough, and many others.
This will seek to strengthen their candidate maintainers public properties by adjusting their speech and behavior in the campaign to the wishes of the electorate.
Sometimes the voting intention poll is combined with a simulation of voting in a ballot box is delivered to the respondent or with different ballots to choose one and "vote".

Opinion polls as a way of sampling

Today mention an error that is usually found frequently in the literature on surveys and opinion polls.
The same is to confuse all the surveys for opinion polls or social surveys. If we wish to clarify what is a survey, or provide a definition, we must make it clear that by no means something that applies to people necessarily.
In fact, the survey is a technique of data collection (some might question how far the data are "collected" as one who takes something that's already been out there and are not created, at least to some extent by those who do research, but that is another problem that will address later) that derives or is an application of the sampling procedure.
Specifically is the use of certain standardized and validated procedures under which the research takes information on a representative sample of a population or universe, as is usually called the total haw investigated.
It is clear that the purpose of such research procedures is to improve our insight of some phenomenon, say a good explanation.
One can conduct a survey in which sample is selected books from a library upon which a questionnaire is completed in some information, because what matters is that the procedure and representative sample.
This, as already mentioned, results from the application of the mathematical theory of probabilities to the investigation of phenomena, whether or not social.
A sample survey differs from a census in which it is to administer a questionnaire to all people concerned, while the survey is always applied to a sample, the best representative.

Opinion Polls and mathematics

Opinion surveys and mathematics.
Sample surveys are the application in a specific area of certain mathematical, in particular of some of the mathematical theory of probabilities procedures or statistical mathematical research.
This are some assumptions based on the assumption that certain operations can be performed with numbers can perform when mathematics no longer pure and becomes applied and represents aspects of social reality.
Made them, is supposed to be possible to measure a specific social aspect, the intensity of the positive image of such candidate, or measure the views in favour, against and indifferent about a specific problem.
Is that the applicability of the procedure of the survey is based on accepted an isomorphism between mathematical properties and properties of social phenomena. Once assumed this, you can use methods and techniques (sample, designs for example) appropriate to establish which is the best way to learn about a certain aspect under investigation.
These methods are standardized and validated, as they are all scientific procedures procedures. It is important to remember that a survey seriously is apply a background of theoretical and methodological knowledge to a social research.

Polietapic sample desing

What is a polietapic sample design?
A sample design polietápico is a type of design research project to collect data from a survey which is divided into various stages of planning and implementation.
These stages cover various criteria that are deployed to reach the final sample, or to individuals that will finally answered the survey.
Let us remember that a sample is a part of a specific population or universe (e.g. a country or a city citizens) is selected to obtain information that will be generalized to the whole population with some margin of error.
As a result, when according to rigorous methodological guidelines, the sample will be representative of this population.
To make this happen, the universe will be successively divided according to different criteria to reach the people you select.
For example may split the provinces or States of a country and select some rightly gaming, dodging, and then in selected provinces applied with a proportionality to the population parameters selection criterion.
If there are 10% of high socio-economic level in the population, determining the sample shall be about that value.

Opinion Surveys

Welcome to opinion polls.
Here we want access to the best resources and information (survey analysis, theory of the surveys, advice, methodology) high quality about the opinion polls and their use.
Particularly include articles, opinions and comments on theoretical and practical aspects of social surveys and opinion polls.
We will discuss issues related to the methodology of the surveys and his theory on the one hand, and other practical aspects relating to applicability in various circumstances and on various types of research.
We want to also discuss teórico-metodológicos aspects related to political, electoral, intend to vote, candidate image surveys and the like.
Also sometimes present comments and some published surveys, we can discuss. Espearmos you can find here what you want from the exciting world of social research through surveys.
