Data Investigator provides professional research data collection and online survey services for academic research, medical and public health research, market research, government research, and business and organisational studies. We recruit qualified respondents from our online panels based on specified research criteria, including demographics, interests, experience and product or service usage. Our data quality procedures include respondent screening and response-quality checks to help ensure that the collected data is reliable and suitable for subsequent statistical analysis. Services are available in both Thai and English, with free initial consultation and quotation. (Click here to contact us via LINE.)

​

Respondent Recruitment Based on Your Research Criteria:

• Respondents can be recruited according to the specific requirements of each research project. Screening criteria may include demographic characteristics, interests, experience, purchasing behaviour, product or service usage and other relevant qualifications.

​

Data Quality and Respondent Screening:

• The quality of research findings depends heavily on the quality of the collected data. Our team applies data-quality screening procedures to identify responses that may not meet the required standards, including unusually short completion times and unrealistic or repetitive response patterns. Responses that do not meet the specified quality criteria can be excluded and replaced with qualified respondents where applicable.

​

Why Reliable Data Collection Matters:

• Reliable data collection is essential to the validity of research findings. Poor-quality responses, unsuitable participants or inconsistent response patterns can affect statistical results and potentially lead to misleading conclusions. Careful respondent recruitment and quality screening therefore play an important role before data proceeds to statistical analysis.

​

Data Collection for Different Types of Research:

• Our data collection services can support academic research, Independent Study (IS), Thesis and Dissertation projects, medical and public health research, market and consumer research, business and organisational studies, human resources research, government research and other survey-based studies.

​

Our Research Data Collection Process​:

• Research Requirement Review: Review the research objectives, target respondents and required sample size.

• Respondent Criteria: Define demographic and other screening criteria.

• Respondent Recruitment: Recruit suitable respondents from the available online panel.

• Survey Distribution & Quality Screening: Distribute the questionnaire and monitor response quality.

• Data Delivery: Provide the collected data according to the agreed project requirements.

​

Online Panel Data Collection:

• Our online panel data collection service enables researchers to reach respondents who meet predefined research criteria without relying solely on open or convenience sampling. Respondents can be screened according to the requirements of each project before participating in the survey.

​

Data Collection for Academic Research:

• For Independent Study (IS), Thesis and Dissertation projects, we can provide data collection support based on the respondent qualifications and sample requirements defined by the researcher. Researchers should ensure that their data collection method and use of external services comply with the requirements of their institution, research protocol and, where applicable, ethics approval.
