                 Data refers to any collection of raw facts, figures, or statistics that can be stored and processed by a computer.
                 It can be in different forms, like numbers, text, images, audio, and video etc.


                         Defining Data Literacy


                 Literacy refers to the ability to read, comprehend, and use information effectively.

                                                      Data  +  Literacy = Data Literacy
                 Data  literacy  means  knowing  how  to
                 understand, work with, and talks about              Data                              Literacy
                 data.  It’s  about  being  able  to  collect,
                 analyse,  and  show  data  in  ways  that                                    Ability to read, comprehend,
                 make sense.                                  Raw facts or figures             analyse, and communicate.

                 Data  literacy  is  essential  because  it
                 enables  individuals  to  make  informed             Data literacy is the ability to understand,
                 decisions,   think   critically,   solve           interpret, analyse, and communicate with data.
                 problems, and innovate.


                         Data Pyramid and Its Different Stages

                 The  data  pyramid  is  a  conceptual  model
                 that  illustrates  the  hierarchical  structure  of
                 data  processing,  depicting  the  progressive                  Wisdom        Why?
                 transformation  of  raw  data  into  actionable
                 wisdom.  It  starts  with  raw  data,  which   How?            Knowledge
                 initially  has  no  use.  Through  processing  and
                 analysis,  this  data  evolves  into  meaningful                                      Who? What?
                 information, then knowledge, and ultimately                   Information            When? Where?
                 wisdom. This transformation enables informed
                 decision-making  and  a  deeper  understanding                    Data                   Raw Data and
                 of the world around us.                                                                   Information


                 Different Stages of the Data Pyramid
                 The DIKW pyramid represents the relationships between data, information, knowledge, and wisdom. Each building
                 block is a step towards a higher level - first comes data, then is information, next is knowledge, and finally comes
                 wisdom. Each step answers different questions about the initial data and adds value to it. Let's learn about them.
