4 min read

The system consists of administering a portion of this population, with characteristics that represent the required audience, and using this percentage to correspond to the total population. It may seem confusing, but through this content, we will provide you with the knowledge you need to start benefiting from or enhancing the positive results that good respondent samples can provide for your business.

How to Define Respondent Samples
To define the samples for a respondent panel, you must take into account some main and extremely important factors. Primarily, we will present you with the 4 main factors that should be considered when defining the sample.
1. Profile, Persona, or Target Audience
The profile or persona is exactly the definition by characteristics of the people you need to answer your survey. It is your target audience! In an electoral survey in Brazil, the entire population over 16 years old, who are people who already have the right to vote, is taken into account. However, in a survey for the launch of a specific product, this target audience can be much more reduced if it is a female product, for example, in this case, your target audience would be women, probably of pre-defined ages, perhaps from a specific geographical location or social class, among other prerequisites.
Properly defining the profile of your respondent sample is of extreme importance, as it will directly influence the result of your study. Therefore, know your research objective well and also the profile of the respondents from whom you wish to obtain information.
2. Probable Margin of Error
As it is a study by sampling, it is impossible to predict with certainty the responses of each individual simply based on the proportion method. Thus, there will always be a part of the final data that would not necessarily be the response provided by the actual respondent.
This margin of error is precisely the maximum percentage difference or variation between the result of the sample survey and the result the survey would have had if it had been conducted with the actual total population.
3. Confidence Level
The confidence level is basically the subtraction of the margin of error. If a survey has a percentage of 80% of people who would like to consume your product and the margin of error is 5% plus or minus, then the confidence level of the survey will be 75% to 85% of people who would like to consume your product. In other words, the market study conducted through a consumer panel, for example, has 90% certainty that the data is accurate.
The market study conducted through online panels is super effective, practical, and economical, and provides incredible and super reliable results.
4. Sample Size
Currently, there are respondent panel software that are responsible for calculating the ideal size of your sample based on factors such as population size and acceptable margin of error, mainly. However, it is important to know how this calculation is done to understand the result of the sample size of your consumer panel.
To calculate the ideal sample size, you must obtain the desired population size and calculate it with the acceptable margin of error to arrive at the ideal number that your respondent population should have.

Types of Research Respondent Samples
As important as knowing the stages of respondent samples is knowing the type of respondents who will participate in your research. There are countless groups of respondents registered in consumer panels, and now, we will present you with the most commonly used ones.
B2C Respondent Samples
This is the largest and least segmented of the groups. It refers to the general population, without any direct professional connection to the market niche in question. These are people who only have an interest and ability to participate in market research and who have very diverse demographic characteristics. Within B2C respondent samples, B2B groups or various other groups with profiles more defined by demographic characteristics, for example, can be formed.
B2B Respondent Samples
This profile is formed by professionals with high decision-making power who work in the market. These professionals are mostly business owners, managers, directors, among others. This type of sample will help you in important business decisions.
Niche Samples
This refers to various groups of respondents classified by similar characteristics. A sample for niche respondents could be a group formed by female lawyers or pharmacists, for example. By contracting our consumer panel, you will immediately have access to thousands of duly registered and classified respondents in niches, ready and qualified to answer your survey.
