This strand of our computing curriculum focuses on the use of and creation of data. In its simplest terms data is a collection of facts, such as values and measurements. It can be numbers, words, measurements or even just observations. Within our daily lives we collect and generate vast amounts of data and often seek to interpret what this data tells us.

Often this involves graphs, charts, tables, indexes, diagrams, photographs, measurements/readings, spread sheets, drawing, notes or databases. Technology can really help to analyse and store data, but it is crucial to learn which technology is best for different types. Below are some useful notes taken from This site explains the handling data process and has further notes on how computers control and measure things, so it is worth a look!

Why Use Computers to Store Data?

It can be useful to use computers to keep track of data. Data that is stored on a computer (as opposed to data written on paper) can be easily:

  • organised / sorted in  different ways
  • displayed / printed in a  variety of styles and layouts
  • searched for specific things
  • updated – adding / changing /deleting items
  • backed-up – a copy can be made with  just a few clicks
  • stored / moved – a memory stick is much smaller than a cupboard full of paper!



What Might You Store on a Computer?

Your Address Book

Most people need to keep track of lots of telephone numbers, postal addresses, e-mail address, etc. We can use a computer (don’t forget your phone is a computer too!) to help keep this data organised in an address database. A typical computerised address book might store:

  • Name
  • Address
  • Phone number (home)
  • Phone number (mobile)
  • Phone number (work)
  • E-mail address
  • Birthday
  • Photograph
  • Etc.

Most address book applications have features that help you organise the records so that you can quickly access the ones you want:

  • Place your entries into groups      (e.g. ‘Family’, Friends’, ‘Work’, etc.)
  • Search (by name, groups, address,      etc.)
  • Synchronisation with other devices      (computer, phone, PDA, etc.)


Results of Surveys

Many groups / organisations undertake surveys to try to discover what people like / want / think.  Surveys can be performed using paper questionnaires, and then the results entered into the computer by:

  • Typing data in
  • Scanning the paper forms, using OMR technology

Alternatively, results can be entered into the computer directly, using an on-screen form (e.g. if using a tablet PC) The survey results are best stored on a computer so that they can easily be analysed. Survey results on a computer allow:

  • Data to be quickly and easily queried (filtered)
  • Charts to be easily created
  • Summary reports to be created



Sales Records for a Tuck Shop

It’s important, when selling things, and dealing with cash, to keep track of the numbers involved. A computer spreadsheet is an good way to record which items you have sold, and also to perform calculations on the data (calculate totals, averages, etc.).  A typical sales spreadsheet might contain the following columns:

  • Item code
  • Item description
  • Item cost
  • Number sold
  • Total cost
  • Profit made
