Data quality refers to the accuracy, completeness, consistency, and reliability of data. In Dubai, ensuring high data quality in quantitative survey data is crucial for making informed decisions, policy formulation, and maintaining credibility in research.

Data quality can be assessed through various measures such as completeness of responses, consistency of data across different sources, accuracy in data entry, and adherence to predefined standards and methodologies.

Common challenges include respondent bias, incomplete or inaccurate responses, language barriers, technological issues during data collection, and errors in data entry or transcription.

Strategies may include rigorous training of surveyors, employing advanced survey techniques, utilizing technology for real-time data validation, conducting pilot surveys to identify and address potential issues, and implementing quality control measures throughout the data collection process.

Data confidentiality and security can be ensured through strict adherence to data protection laws and regulations, secure data storage systems, encryption methods, limited access to sensitive information, and anonymization techniques.
