Key benefits from research

Surveys allow you to make decisions under conditions of uncertainty. Having the results of a survey of a representative sample, you are 95% likely to make the right decision.

Opportunities of the method

Online surveys are by far the most popular way to collect information. Its advantages are:

1. Low cost (an online survey is cheaper than any other types of surveys);
2. Efficiency (in just two or three days you can collect the opinions of several thousand respondents and draw conclusions based on these data);
3. Accuracy (errors and the “human factor” of interviewers are excluded: consumers themselves answer the survey, the questionnaire follows a programmed script);
4. Reliability (profiles are checked using calls, operators are trained and regularly listened to by call center supervisors);
5. Unlimited geographical coverage (the modern level of telephone coverage makes it possible to conduct interviews with all categories of the population, including hard-to-reach groups: the population of villages and hamlets, elderly respondents, teenagers).

The only limitation of online surveys is the duration of the survey. It is difficult for respondents to answer the interviewer's questions for more than 5-7 minutes. In other cases, online surveys are the most effective method of collecting information in terms of cost and timing.

Sample size and timeline

The minimum size of a representative sample for surveys per region ranges from 400 to 2000 questionnaires. By region we mean any territory for which separate analytics is required (this could be, for example, a city or country). In cases where it is necessary to separately consider and compare data, for example, London and Paris, the minimum sample is 800 questionnaires. The minimum period for such a survey is 1 business day.


The cost of conducting a survey consists of the cost of collecting a selected number of questionnaires (payment is taken only for fully completed questionnaires) and the cost of analytics (usually no more than 10-15% of the cost of data collection)

You can calculate the cost of one questionnaire yourself using our calculator (you will need to enter the number of open and closed questions in the questionnaire, quotas)

The cost of such a study is from 1000 £ (the cost is indicated for a minimum sample).

Description of the approach

Online surveys are conducted on BCGroup’s own platforms located on its servers. The questionnaires are programmed in accordance with the required logic, and quotas are set in the program. We can also offer survey branding with your logo or the logo of our partners. The program keeps statistics on passing quotas, refusals and other parameters. BCGroup is also constantly working to expand the online panel of respondents not only in 146 countries of the world.

Telephone interviews (CATI) are conducted by call center operators in a special program (developed specifically for the needs of BCGroup) with recording and the ability to listen to conversations. Before the launch of each project, operators are trained, test questionnaires are collected (project piloting) - at this time the Customer can adjust the work of operators, give recommendations, and also make changes to the questionnaire. After all adjustments are made and approved, the project is fully launched.

All conversations between call center operators during each project are recorded. This includes records of imperfect interviews: in cases of refusal to interview, failure to complete quotas or interrupted interviews. Full statistics are also kept on the following parameters:

1. Total number of calls;
2. Effective interviews;
3. Incomplete interviews;
4. Failure to pass quotas;
5. Survey refusals;
6. Category “Call back”;
7. No answer;
8. Incorrect phone number.

The recordings are provided in mp3 format, the name of each file is the number of the questionnaire in the array, the date and time the interview began, and the respondent’s telephone number with city code.

The database for conducting telephone surveys is either a pre-prepared database provided by the Customer, or randomly generated telephone numbers (with the required prefix).

The call center of the research agency BCGroup collects up to 45,000 questionnaires monthly.

Process of research

BCGroup's work in conducting a survey of consumers or the public is structured as follows:

1. A BCGroup specialist studies the questionnaire provided by the customer (if the questionnaire is provided) or draws up a questionnaire to solve the assigned tasks, agrees on the geography of the survey, as well as quotas;
2. BCGroup tests the survey questionnaire on the target audience, if necessary, makes suggestions for adjusting the questionnaire: wording, order of questions, additional answer options and much more;
3. In the case of a telephone survey, a BCGroup call center employee prepares databases for the survey and coordinates them with the customer;
4. BCGroup call center interviewers undergo training, take test questionnaires, and ask questions if necessary;
5. BCGroup conducts surveys in a short time (it is possible to survey up to 5,000 people per day);
6. Next, the BCGroup employee transfers the data array to the customer’s representative in Excel or SPSS format and audio recordings of the interview in mp3 format;
7. If necessary, after 3-5 days, a BCGroup employee sends an analytical report to the customer based on the results of the analysis of survey responses.
