# Data Handling: Data Collection And Organization Of Data

Data handling is the method of performing statistical analysis on the given data. What is Data? Why do we need it? Data are individual pieces of information, information about a particular system. The average human body temperature is 37oC, which is data. The number of students in your class is also data. Data is made useful by data collection, data organization and it is finally processed through data analysis. Data handling is the process that comprises of data collection, data organization, data analysis and finally its depiction with the help of graphs or charts.

Data handling comes extremely naturally to us. When someone asks you how old you are, you give them a number, correct. Do you know you just handled data! Your age is a data, your height is a data and your roll number are all data! You are basically handling data already! When I said data handling comes naturally to us, I forgot to mention that some of us are better at handling data than others. I myself was never good at remembering birthdays and numbers, but if you are; then congratulations guys, you already must be pretty good at it! Now every single person in the world is constantly interacting and generating data; your mails, you messages all contain data in large quantities. The industry uses the process of data analysis to make such large amounts of data useful to us.

## Data handling Definition

The temperature of the surface of the sun is 5000oC. So how does this data help you? This data is useful when we think about the 5000oC and realize that this means that the surface of the sun is very hot! The data that the sun’s temperature is 5000oC becomes information when it leads to a realization that the sun is very hot. Information is the interpretation and understanding of data.

What you handle day to day is called Raw Data, this kind of data by itself does not have any meaning. Let’s take any test you may have recently had at your school. You have a fixed and known numbered students in your class. The marks that you get is the data here. You can see that your marks by themselves don’t mean much to anyone but you right? If I wanted to know how your class performed in the test then just your data is no good. Its only when the data is organized and processed that it is useful to us. Say for example, the teacher who took your test instead of putting your names alongside the results put it randomly. Would it make any sense to you? What would you do if you wanted to know your scores? So the randomly arranged marks is exactly how data is available to us. It’s only after its organized and structured properly that it is of any use or meaning to us.
