Question

In a survey the term 'Quality' is often used in a general way in data processing. How would you better define data quality bearing in mind the concepts of Quality Control (QC) and Quality Assurance (QA)? Quality concerns only the validity of numerical data. QC concerns incompleteness of data while QA concerns the correctness of the data. In the case of a survey, quality encompasses either QC or QA. QC concerns incompleteness of data while QA concerns the correctness of the data. In the case of a survey, quality encompasses both. Quality Assurance is not used in surveys unless the resulting dataset is large.

Explanation / Answer

Data quality control is the process of controlling the usage of data with known quality measurements for an application or a process. This process is usually done after a Data Quality Assurance (QA) process, which consists of discovery of data inconsistency and correction.

Hence, the correct answer is C. Both are used in quality testing.
