                     Before starting the chapter, think about all the things you know about the world
                     around you. Every time information  is collected,  it  becomes  data.  Data can be

                     things like a person’s name, age or favourite food. In this chapter, you will learn how
                     to collect, sort and show data in different ways.

                     UNDERSTANDING DATA

                     Data refers  to  raw  facts  or figures that  provide  us with information  about  the

                     world around us. It can come  in many  forms, such as words, numbers  or even
                     pictures. Imagine looking around you and noticing things like the colour of your
                     clothes, your favourite toys or the pets people own. All of this information is data.

                     When data is collected, it helps people make decisions, solve problems or learn
                     more about something.
