| description | For growth and development in different fields, research and studies are extremely important. For ensuring the success and credibility of these studies, it is often necessary to do surveys and have the target audience fill up questionnaires. These surveys and questionnaires are, however, prone to missing data. The objective of this report is to understand the types of missing data that researchers often come across, and furthermore, to comprehend the previous works done on handling missing data in these questionnaires. Also, this report discusses the methods implemented and tested by the author, a comparison of the various methods tested, followed by the conclusion based on the results of this testing so as to understand the best method available for handling missing data. |
