Data validation/checking is an important part of any process that involves large volumes of data. The received data may need to be cleaned, validated and corrected (especially important for paper questionnaires)
To ensure the quality of data, we do the validation (cleaning) of data using Quantum and SPSS. Our experienced data validation professionals ensure that the data does not contain any unwanted codes, errors or inconsistencies. The data is edited using various logical checks as per the questionnaire and study objectives provided by the client and corrected as per the client's feedback.
