BSC ESTEK conducts human research survey of public opinion from a particular sample. These surveys are designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals.
Our survey methodology studies the sampling of individual units from a population and the associated survey data collection techniques, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.
We work and have experience in various fields, such as market and economics, politics, ecology, sociology, and so on.
Quantitative research is research involving the use of structured questions where the response options have been predetermined and a large number of respondents is involved.
We do our best to keep our measurement objective, quantitative and statistically valid. Simply put, it’s about numbers, objective hard data.
The sample size for a survey is calculated by statisticians using formulas to determine how large a sample size will be needed from a given population in order to achieve findings with an acceptable degree of accuracy. Generally, researchers seek sample sizes which yield findings with at least 95% confidence interval (which means that if you repeat the survey 100 times, 95 times out of a hundred, you would get the same response) and plus/minus 5 percentage points margin error. Many surveys are designed to produce smaller margin of error.
Qualitative Research is collecting, analyzing, and interpreting data by observing what people do and say. It refers to the meanings, concepts, definitions, characteristics, metaphors, symbols, and descriptions of things.
Qualitative research is much more subjective than quantitative research and uses very different methods of collecting information, mainly individual, in-depth interviews and focus groups. The nature of this type of research is exploratory and open-ended. Small numbers of people are interviewed in-depth and/or a relatively small number of focus groups are conducted.
Participants are asked to respond to general questions and the interviewer or group moderator probes and explores their responses to identify and define people’s perceptions, opinions and feelings about the topic or idea being discussed and to determine the degree of agreement that exists in the group. We engage skilled, experienced and sensitive interviewers or group moderators in order to achieve high quality findings.
