Data handling is the process of ensuring that research data is stored, archived or disposed off safely and securely during and after the conclusion of a research project. Data Handling is also sometimes known as statistics, and you will often come across it in the study of both Math and Science. It includes the development of policies and procedures to manage data handled electronically as well as through non-electronic means. Chapter 33 deals with the study of data in the form of frequency distribution table, pictograph and bar graph to represent the given set of data.
