    forms or important groups of people are left out, meaning the data does not give a
                     true picture.

                     Here are some examples of how data can go wrong and why it matters:

                      Inaccurate Data: A thermometer sensor placed in direct sunlight will always
                        show a temperature much higher than the actual room temperature, making

                        the data inaccurate.

                      Incomplete Data: A survey about favourite school subjects that is only given to
                        students in the science club will not represent all students fairly. Students who

                        love art, music or languages won’t be included.

                      Unfair Data: A school database where some students’ dates of birth are entered
                        incorrectly will give unreliable results when studying how age affects learning.

                               Data is the raw collection of facts, figures, symbols or observations that represent
                              details about events or objects.

                               Data doesn’t appear out of nowhere. It is collected from the world around us every
                              minute of the day.

                               Structured data is information arranged in a clear and tidy way, usually in rows and
                              columns, just like a table or a spreadsheet.
                               Unstructured data does not follow a fixed pattern.

                               Machines collect data without any help from humans. They do this all day and night,
                              without stopping.

                               A database is like a large, well-organised digital cupboard. Instead of paper files and
                              folders, it keeps information in electronic tables. These tables are organised in rows
                              and columns.
                               Sorting means putting data in a particular order.

                               Filtering  means  showing  only  the  rows that  match  a  condition  you  set  and  hiding
                              everything else.

                               Good data is data that we can trust. It helps us make decisions or learn more about
                              something.
                               Bad data is inaccurate, incomplete or unfair.

                                                                                          Good Data and Bad Data      33
