Voluntary Response Sample
Table of Contents

In the realm of market research, where data is a commodity, sampling methods play a crucial role in ensuring the accuracy and reliability of findings. One such method is voluntary response sampling. 

In this blog, we will delve into the intricacies of this sampling method and explore how it is useful in certain contexts but challenging in others. 

What is a voluntary response sample?

A voluntary response sample can be defined as a sample made up of participants who have voluntarily chosen to participate as a part of the sample group.

Participants in a voluntary sampling usually choose to respond to surveys because they have a strong opinion on the subject of the survey.
Voluntary samples are easily accessible.
Due to the convenience of gathering data from interested participants, data collection is faster.

All this can also lead to voluntary response bias, as most of those who participate will have a strong opinion about a topic in either direction. Another reason why people participate is due to the convenience of joining the survey.

Voluntary response sampling is considered a type of non-probability sampling technique because participants are self-chosen and not selected by the researcher on a random basis.


How can you collect voluntary response samples?


Some common methods you can use to collect voluntary responses are online surveys or phone surveys. These methods rely on individuals taking the initiative to respond. While voluntary response samples can be convenient and cost-effective, they are also prone to bias, as respondents may have different characteristics or opinions than those who choose not to respond.

Uses of Voluntary Response Sampling

Voluntary response sampling is not advantageous or applicable in most studies as it is highly susceptible to bias and yields unreliable results. Instead, other sampling techniques should be used such as simple random sampling, stratified random sampling, or even purposive sampling.

Because of its disadvantages, voluntary response sampling is not suited to studies where the aim is to create unbiased results. However, there are some cases where a voluntary response sample can be useful. For instance, it can be used by the entertainment industry by talk show hosts or radio hosts. When people watch talk shows or listen to the radio, they want to hear strong and unique opinions. In such cases voluntary response sampling is apt as respondents that do give their opinion, will likely have a really strong stance on the subject.

Some organizations employ the use of voluntary response sampling in promotional or marketing strategies to advertise their products. They can use it to influence existing customers to start advocating for the brand. This improves the organization’s brand image which will in turn have positive effects on sales, revenues, and profits.

Example of using voluntary response sample 

An example of a voluntary response sample is when TV show hosts of competitions, such as the American Idol, ask their viewers to send in their responses about who they think should win the competition. Only viewers who have strong opinions on who should win will send in their votes. Viewers who are indifferent toward the show and its competitors will not send in their votes.

What is voluntary response bias?

When participants self-select for a survey, you only gather data reflecting the sample and not the entire population. This often leads to gathering more extreme results than what the target population experiences. As a result, your research falls victim to a voluntary response bias.

Customers who had extremely positive or negative experiences with the brand may be motivated to share their feedback compared to those with neutral experiences. This can cause biased results suggesting a strong like or dislike towards the brand, thus misinterpreting the overall customer sentiment.

How can you recognize voluntary response bias?

Let’s look into some characteristics of voluntary sampling to learn the indicators that can help us identify this bias.

1. Limited representation:

The sample and the survey result may not represent the population accurately. For example, if you share your survey via online channels, it will only attract audiences who have access to these channels. This will potentially exclude a large portion of the population who may have knowledge but are unable to access online surveys.

2. Extreme opinions:

Your survey findings will demonstrate strong opinions, that is, with higher responses of extremely positive or negative responses. This indicates a skewed interpretation of the population.

3. Limited generalizability:

Due to the voluntary response bias, the findings may not be applicable to the entire population. It’s essential to identify if the survey findings represent the target population to recognize the limitations of your research scope.

Advantages of voluntary response sample

Selecting participants who take the survey can be time-consuming and may not always result in high response rates. Voluntary sampling can, however, overcome this. Here are some advantages of this sampling method.\1. Higher engagement:

Voluntary response sampling can lead to higher engagement from participants as they actively choose to participate in your research. This can result in more considered and authentic responses, leading to meaningful insights.

2. Building community:

This can also help you build a sense of community between the participants and the company, especially in longitudinal studies. It can lead to higher retention rates and more reliable data over the long term.

3. Timeliness:

It is also a quick way to gather data, especially when you use online surveys. You can gather responses rapidly and analyze the data in a timely manner.

4. Easy implementation:

You can easily implement voluntary response samples by distributing your surveys through accessible platforms like online channels or telephone surveys. This gives you an easy way to connect to more people and allows for straightforward data collection.

5. Genuine insights:

Mostly, voluntary response sampling consists of people who have a genuine interest in your research subject. This enables you to gather diverse perspectives and accurate insights into the topic.

Disadvantages of voluntary response sample

Voluntary response bias can skew the data and misinterpret the entire population. Let’s look into the disadvantages of this sampling method that you should keep in mind.

1. Biased responses:

As members in a voluntary response sample are self-selected volunteers, they tend to have a stance on the topic that falls in either extreme. This gives rise to biased and unreliable results.

2. Errors in data quality:

Highly biased responses will lead to an extremely low quality of data collected. Calculate your margin of error using a margin of error calculator.

3. Lack of coverage:

A lack of coverage occurs when members of a population are not appropriately represented in the sample. Taking the example discussed above, only viewers of the TV show will give in their votes. People who do not follow the show or have a neutral opinion on the performances will not participate in the survey and will not send in their votes.

How can a market research panel help create a voluntary response sample?

A market research panel, like Voxco Audience, can be instrumental in voluntary response sampling. It provides a pre-recruited group of individuals who have agreed to participate in research studies. These panelists are recruited based on various demographics, interests, and behaviors, allowing you to target segments of the entire population. 

  1. Utilizing a research panel gives you access to a diverse pool of respondents to ensure a more representative sample. 
  2. Panels employ measures to verify and maintain the quality of their panelists, thus reducing the risk of fraudulent or duplicate responses. 
  3. It allows you to quickly access a large number of respondents, making data collection more efficient. 

Voxco Audience enables you to tap into a vast pool of 10Mn+ B2C and B2B professionals across 50+ countries while ensuring quality and increased sample feasibility. 

With 60% proprietary samples and 90+ data & profiling points, it lets you add panelists without leaving the platform, cutting down the time of research from months to hours.
