It encompasses both electronic and non-electronic means of data management to ensure the data’s safety and security at all stages.
Statistics is another term for data handling, and it is useful not only in the fields of Math and Science but also in the fields where the representation of data is required. Let’s learn about some forms of Data handling, including the graphical representation of data and how they work.
