Data Capture
“DATA CAPTURE is gathering information to put on a
computer system”

Starter: In pairs, think of 3 companies that might use data
capture. Think about why they would want to gather the
information.

For example, a library may have a form for new members
to fill in to register.

Discuss your answers with the class
Data Capture
 You have to record the information in   You have to actually enter the data
 a suitable form.                        onto the computer.




Data capture turns information into data… so
how do we get the information on to the
computer?
Manual methods


               Forms                                   Questionnaires




Manual methods include forms and questionnaires. Someone writes out
information in a set way (e.g. on a form). It’s then input into the computer
exactly the way it was written on the form.
Manual methods
 Questionnaires usually need someone to
  key in the results by hand.

 With data capture forms, you just enter      How do you get to school?
  information in code format. The               A. Walk
  information is automatically read using a     B. Car
                                                C. Bus
  scanner –type thing. E.g. multiple choice     D. Train/Tube
  answer sheets or some school registers.

 Turnaround documents (e.g. electricity
  meter reading forms) use a semi-automatic
  system. The computer prints a personalised
  form with a space to record the meter
  reading. The customer writes the reading
  by hand, then the electricity company add
  the new data to the customer’s record on
  the computer.
Automatic methods
• Automatic data capture means collecting data from sensors, bar code
  readers and scanners. E.g. when the assistant scans shopping at the
  supermarket .

• How many other places can you think of that use barcode scanners?

• Smartphones can also capture data by scanning. Watch this news report to
  find out how.

sheet
Data capture form design - Rules
1.    Keep the layout simple and leave enough
     space to write the answers. Don’t put the
     answer boxes too close together.

2.   Write down instructions on how to fill out
     the form.

3.   Make it look interesting.

4.   Only ask for necessary information.

5.   Check the form for accuracy and
     completeness before it is printed.

6.   Test it! Try it out on a small sample of
     people.
