Data Management

At Preston Associates, we specialize in providing comprehensive data collection and analysis services tailored to suit the unique needs of our clients. Through our data-driven approach we empower organizations to make informed decisions, drive innovation, and achieve sustainable growth. We are committed to delivering accurate, reliable, and actionable data void of bias and incompleteness. We utilize a combination of traditional and innovative data collection methods and tools, including surveys and questionnaires, interviews and focus groups, web scraping and data mining and machine learning in the immediate future.

Our proprietary data collection platform, the Iwadii App, enables seamless integration and automation, ensuring efficiency and accuracy in data capturing. We also utilize popular software applications such as, Redcap, Survey CTO, KoboCollect, CSPro, ODK Collect and others.
To ensure data accuracy, completeness, and consistency, we employ robust validation checks and protocols, using software and back-end data validation techniques. In our data quality assurance process, we implement high-frequency checks, back-checks, and spot-checks which are used to detect programming errors, surveyor errors, data fabrication, poorly understood questions, and other issues. These checks specifically help us identify anomalous entries or submissions, ensure consistency across related variables, validate the survey program’s functionality, assess enumerator performance, and evaluate overall data quality metrics such as missing values, non-responses, timing, and dates. Drawing from our extensive experience in field and project management, we employ Computer Audio-Recorded Interviewing (CARI) techniques to maintain response integrity during data collection. These audio files are used solely for quality enhancement purposes. and are not retained after data quality checks are completed.
