                     Once data is collected and organised, it becomes easier to study and understand patterns in it.

                     Structured and Unstructured Data

                     Data is information that is collected and used to understand patterns, make predictions or gain
                     insights. It can take many forms such as numbers, text, images or sound. Data can be organised
                     in different ways, which helps you understand and use it better. There are two main types of data:

                     structured and unstructured. Let’s explore both types of data:

                     Structured Data

                     Structured  data is  well-organised  and  follows a clear format.  It is  usually  found  in  tables  or
                     spreadsheets,  making  it  easy  for  you  to store, search and analyse. Since  it follows  a defined
                     pattern, you can quickly organise and access the information.
                     Examples of structured data include:

                      A table of student marks

                      Attendance records
                      Sales data in a spreadsheet

                      A school timetable
                      Results from a science experiment with measured data

                      A list of books in a library with titles, authors and publication years

                     Unstructured Data

                     Unstructured data does not follow a fixed format, which makes it harder to store, organise and
                     analyse. This data includes many different types such as text, images or audio. Unstructured data
                     often requires more effort to process and interpret.

                                                                                     Data Visualisation and Analysis   47
